Learn Ordinal Numbers 1 to 100: Fun & Easy Guide for Hindi and Urdu Speaker | Udable

[lilith-hazel-mathematics]

Set theorist count to 100 challenge. Difficulty: impossible

Hey mathblr, let me tell you about my favorite activity ever: counting!! Let's all count to 100 together :)

But with a twist: you have to do it like a set theorist! We'll write out each Von Neumann Ordinal using nothing but curly brace list notation. Each Von Neumann ordinal obeys the rule n={0,1,...,n-1}, so for example 10={0,1,2,3,4,5,6,7,8,9}. To play the game, you have to write the next number without typing any Arabic numerals. Lilith will start us off with zero, then I'll take my turn and count to 1, and then someone else can go!

Hi there, really informative and interesting blog, big thanks for the work :) How would you say a weird ordinal number like 49257th? I read your post on ordinals and found scant more searching the interweb. Cheers! - Planetarywalker

I believe it would be: cuarenta y nueve milésimo/a ducentésimo/a quincuagésimo/a séptimo/a

In general, people don't like to use the ordinal numbers after 10

And they definitely don't like to use them after 100; because EVERYTHING has to be adjusted for gender

...The reason for that is when you do ordinal numbers like this, every "benchmark" number has one of the -ésimo words... the numbers in the thousandth, hundredth, tenth and the last number are all specialized which makes it very tedious

In your example: cuarenta y nueve milésimo/a is "49 thousandth", then ducentésimo "two hundredth", then quincuagésimo/a "fiftieth" + séptimo/a "seventh"

Whether it's all masculine or feminine depends on the gender of the thing

...The ordinal numbers primarily past 20 are combined; so vigésimo/a primero/a is "twenty-first", so that's why 57 is combined like that; you have the number in the tenth position + the ordinal number 1-9

To make it worse, primero/a can be primer in front of masculine nouns, and tercero/a for "third" is tercer in front of masculine nouns so it would be even more annoying

You are very rarely going to have to say el vigésimo primer libro "the 21st book"

-

Typically, if a native speaker saw this they'd probably say something like... cliente número 49257 [cuarenta y nueve mil, doscientos cincuenta y siete]

Even centuries are listed in cardinal numbers instead

el siglo XVIII is "the 18th century", literally "century 18"

No one has time to say el vigésimo siglo instead of siglo veinte for the 20th century

And monarchs will get ordinal numbers between 1-10, like Alfonso X (décimo), but you'll see Luis XIV [catorce] instead for "Louis the 14th"

Again; native speakers have no time and patience for ordinal numbers and they will avoid them as much as possible and God help you if you give them a number that isn't even 100, 200, 300... give them 207th and they'll probably just say doscientos/doscientas nueve instead

Norwegian possessive pronouns

ok this is probably incorrect usage but for the purposes of this post by "subject" I mean subject who owns the "object" not the actual subject of the sentence.

Possessive pronouns in Norwegian depend on the subject and object, specifically the ordinal number person (1/2/3) the count of the subject (singular/plural) and the count of the object (singular/plural) and the gender of the object (masc/fem/not). In most cases the possessive pronoun is the same as the reflexive, except for third person. Where the reflexive does not depend on the subject's gender(masc/fem), but the regular possessive one does.

the difference between reflexive and not is

A looks at A's shoes -> reflexive (she looks at her shoes -> hun ser på skoene sine)

A looks at B's shoes -> not (she looks at his shoes -> hun ser på skoene hans)

(one exception shown below) (I believe that's right but I'm not 100% cause no sources mentioned it but I'm a bookworm & native speaker)

Possessive pronouns are usually after the noun. You can generally write it before I think, but it often sounds odd. You can use it to emphasize who possesses the object though "det er min bok, ikke din!!" -> "it's my book, not yours!!'. But if you write the possessive pronoun before you have to make the noun "undefined" ("boken min" -> "min bok") Norwegian "ubestemt form".

ok so the format is: subject: singular masc object / singular fem object / singular non-gender object / plural object

1. person singular subject: min / mi / mitt / mine

2 person singular subject: din / di / ditt / dine

3 person singular subject reflexive: sin / si / sitt / sine

3 person singular subject masculine: hans

3 person singular subject feminine: hennes (booknorwegian)

3 person singular subject feminine: hennar (newnorwegian)

(it seems "den" og "det" subjects can't own anything) (I'd use "dets" or "dens" though, or the "[noun]s" using "genetiv s" if you want to search it up)

1 person plural subject: vår / vår / vårt / våre

2 person plural subject: dere / dere / deres / deres (booknorwegian)

2 person plural subject: dykkar or dokkar

3 person plural subject: dere / dere / deres / deres (booknorwegian)

3 person plural subject: deira (newnorwegian)

3 person plural subject reflexive: sin / si / sitt / sine

my ref for details: gramatikk.no pronomen (booknorwegian) , gramatikk.no nynorsk, wikipedia nynorsk for determinativ

examples (booknorwegian):

Hatten min er blå -> My hat is blue / Hat my is blue. (hatt=masc defined singular).

Han kjenner til bøkene hennes -> He knows of her books / He (knows to) ((the books) (her)). (hennes is not affected by what is being owned)

Kortet er mitt -> The card is mine. (kort=non-gender defined singular).

Vi lever våre egne liv -> We live our own lives (same word order)

Bøkenes deres ligger i hattene våre -> Their books are in our hats.

Ikke rør teppet mitt -> Don't touch my blanket / Don't touch my carpet.

Teppet deres er blått -> Their carpet is blue. (teppet=defined, non-gender, singular)(blått=non-gender)(deres=2nd or 3rd person, nongender or plural).

Alle vet det er min bok -> Everyone knows it's my book (same word order)

Idk what's up here, but the whole reflexive thing is complex:

Han vet at kortet hannes ligger på bordet -> He knows his card is on the table / He knows that the (card his) (lies on the table). (note two verbs)

Han ser kortet sitt på bordet -> He sees his card on the table / He sees card his on the table. (note one verb)

examples (newnorwegian):

Det er deira fortelling -> It's their story. (plural they).

Boka hennar ligg på bordet -> Her book is lying on the table / Book her lies on the table (Norwegian word order) / Her book is on the table. -> Boka hennes ligger på bordet (Booklanguage)

Friday with Old Moonwingian - Counting

Ameniši!

Today in my fairy conlang lesson we'll take a look at the counting systems. Yes, plural! There are three different sets of numbers you use for different purposes.

Personal

This system is used for counting people and overall sentient beings. If the stuff you count can communicate using language, then you use the personal system.

The system mixes decimal and vigesimal, but also throws in a bit of quinary.

Non-personal

Self-explanatory. You use this system when counting anything that doesn't fall under the personal system.

It's a similar mix of decimal, vigesimal and quinary as personal, but also is the only one with its own word for a dozen.

Magical

This is a special system used only for casting spells. It serves as a case of whatever the opposite of avoidance speech might be as it is used specifically to strength the spells. The fairies living on Moonwing Islands believe that these numbers have special powers inside them and as such help with magic.

It's completely decimal.

Now let's compare the three systems. On the left there will be the personal system, in the middle the non-personal and on the right there will be magical

0 - Mem / Mem / Kafe

1 - Lam / Olin / San

2 - Tem / Tim / Son

3 - Sem / Sem / Ken

4 - Pin / Pom / Kim

5 - Kin / Sä / Šin

6 - Lan / Li / Kalin

7 - Ten / Ti / Pim

8 - Sen / Se / Pakin

9 - Pen / Tom / Takin

10 - Telen / Tin / Sin

11 - Telen lam / Tin olin / Sin san

12 - Telen tem / Täsen / Sin son

13 - Telen sem / Tin sem / Sin ken

15 - Sem kin / Sem sä / Sin šin

20 - Tälen / Tolen / Son sin

30 - Tälen telen / Tolen tin / Ken sin

35 - Tälen sem kin / Tolen sem sä / Ken sin šin

40 - Tem tälen / Tim tolen / Kim sin

100 - Hilen / Halen / Šam

10000 - Sänte / Säka / Šäkke

86239 - Sen sänte sem tälen tem hilen tälen telen pen / Se säka sem tolen tim halen tolen tin tom / Pakin šäkke kalin sin son šam ken sin takin

The difference between cardinal and ordinal numbers is placement in the sentence. Place it before the thing you count and it's cardinal. After the thing you count and it's ordinal.

That will be all for today!

Numeral Exercises

        NUMERAL DEFINITION AND EXERCISES

In English grammar, numerals function as a part of speech to represent numbers, quantify nouns, and express numerical relationships. There are two main types of numerals in English: cardinal numerals and ordinal numerals. Cardinal Numerals: Cardinal numerals represent specific quantities or numbers. They answer the question how many? and are used to count objects or denote a precise quantity. Examples: One, two, three, four, five, six, seven, eight, nine, ten Eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen Twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety One hundred, two hundred, three hundred, etc. One thousand, two thousand, three thousand, etc.   Ordinal Numerals: Ordinal numerals denote the order or rank of items in a sequence. They answer the question in what order? and are used to indicate the position of something in a series. Examples: First, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth Eleventh, twelfth, thirteenth, fourteenth, fifteenth, sixteenth, seventeenth, eighteenth, nineteenth Twentieth, thirtieth, fortieth, fiftieth, sixtieth, seventieth, eightieth, ninetieth Hundredth, thousandth, millionth, billionth, etc.   Numerals can function as determiners when they directly modify nouns, indicating the quantity or position of the noun. For example: Cardinal Numeral as Determiner: Three apples fell from the tree. Ordinal Numeral as Determiner: The first prize goes to the winner.   Numerals can also function as adjectives when they modify nouns but do not directly specify quantity or order.  For example: Cardinal Numeral as Adjective: She bought two pairs of shoes. Ordinal Numeral as Adjective: He is in his third year of university.   Additionally, numerals can function as nouns themselves, particularly when referring to numbers as concepts or entities. For example: The number eight is considered lucky in some cultures. She divided the class into groups of four.       Instructions: Please, do the exercises without seeing the Answers.

#1. Sword Art Online⚔

❗WARNING - DARK THEMES❗

I have words upon words upon words upon words that I could say about this show, but I will try my best to keep it fairly concise.✍🏻

The biggest reason that I've been attached to this show is because of the main character, Kirito. In the beginning of this show, he's young and lost. He reminded me quite a bit of myself & who I was growing up. I will be sharing ❗spoilers❗ from here on out. So, if you'd like to watch the show (& haven't yet) - all I'm going to say is that it's worth it.

Starting with his survivor's guilt that he has over his fallen guild, I too have held myself responsible for things that I thought, "if I had just shared this info," or "told them that one thing," I could have changed fate. I've held responsibility in my hands over things not quite as heavy as watching a group of friends die, but on things that weighed on my heart too. Just like Kirito, I find myself taking the blame and burden for things around me - even when it's outside of my control. He had no idea that his guildmate would fall for the trap and he desperately tried to stop them before it happened; he also fought tooth and nail just to make it out of there alive. He was 14 at the time; he did what he could, but he blamed himself anyways...and honestly, I would have done the same.

The next thing that I immediately gravitated towards with him was the fact that he cut himself off from everyone because he was afraid to hurt anyone else. To say that I've done that would be sugar coating it🙃. When I was younger (& even still some today), I shoved people away - people that I loved at the time, because I felt like I was a monster, a burden. He felt that with being a "Beater" (Beta Tester/Cheater), he put others' lives in danger and instead of risking it ever again - he was the lone, black swordsman. I felt that loneliness with him. I understand what it feels like to imagine that the world would be better off if you were just a person passing by - not causing any troubles. It's lonely, but you think you're doing everyone else a favor by not getting in the way. You're sad when you go to sleep at night, but you desperately try to tell yourself that you're "doing the right thing" in order not to fall asleep in tears.

As he grows and gains friends (that sometimes he had 0 intent to have), I also feel that emotion with him. Over the years, I've allowed myself to open up a bit more and allow others into my life; just like he did. I also watch him time and time again put his life on the line for those friends - people he deems worthy to keep on living. I resonate with that idea and that passions because I would also put my neck out for those who I loved and saw as "family."

Over and over, he's thrown new situations and dilemmas that he has to do his best to adapt to. I, as well, have had to deal with the curveballs of that life has thrown my way and take it in stride. Kirito and I both do our best to act like we're 100% okay on the outside and push aside our emotions, but deep down - we're both broken and very emotional human beings. He bottles it all up, just like I do. We're the same in many, many ways.

I'm really putting my heart on the line with this post, but if you ever want to "get to know me" better, watch Sword Art Online and realize that Kirito is a lot of my bad, but also a lot of my good. We're both human and really think along the same lines of what we'd do for ourselves and those around us. There's a big reason why he's stayed my number 1 for 8 years (about the amount of time I've been watching Anime as well😅).

This guy really deserves to smile after the years of agony that he's been through - & so do I. 🖤

I love this show so much that I've seen every season at least twice through (Season 1 more like 6-8 times) & I've seen/own the movie (Ordinal Scale). It is by far my favorite and easily my comfort show. So, if you watch it, I hope you enjoy it too!

A practical guide to obtaining an apostolic blessing from Pope Leo XIV

Pope Leo XIV is now granting apostolic blessings to the faithful around the world, a spiritual gesture that can be officially requested through the Vatican’s Apostolic Almoner’s Office.

These blessings, printed on parchment, are a well-established tradition in the Catholic Church and are available for significant moments in Christian life such as the sacraments of baptism, confirmation, and marriage.

As indicated on the website of the Vatican Apostolic Almoner’s Office, the procedure for obtaining an apostolic blessing can be completed in two ways: in person at the offices of this department or through an online form.

Those who choose the in-person method should go to the offices located within Vatican City, entering through the Porta di Sant’Anna, to the right of the colonnade in St. Peter’s Square. Office hours are Mondays, Wednesdays, Fridays, and Saturdays from 8:30 a.m. to 1:30 p.m. and Tuesdays and Thursdays from 8:30 a.m. to 5:30 p.m. local time.

For those not in Rome, the digital process is equally accessible. Through the official website of the Apostolic Almoner’s Office — the only authorized site for this purpose — applicants must follow several steps.

The first step is to select the occasion for which the blessing is being requested (such as a baptism, marriage, or anniversary); then, choose the style of parchment; then, enter the information that should appear on the document; and finally, register the applicant, choose the delivery method (local pickup in Rome or shipping via DHL Express), and make a donation by credit card (only Visa and MasterCard are accepted).

The requested information includes the full name of the recipient(s) of the blessing, the specific occasion, the date and location of the event (in the case of sacraments or anniversaries), as well as the sender’s complete address, email address, and phone number. The system also allows users to open a personal account for future requests. Once the transaction is confirmed, the Apostolic Almoner’s Office will send a confirmation email with the estimated delivery or pickup date.

The processing time for the request is approximately 25 days if picked up at the Vatican office and 30 days for international deliveries. The cost of the parchment ranges between 20 and 30 euros ($23-$34), depending on the style, plus shipping costs, which vary depending on the destination, from 15 euros ($17) for destinations within Italy to 40 euros ($45) if sent to Africa.

It is worth noting that, after deducting the processing and shipping costs, all proceeds go entirely to the charitable works carried out by this office in the name of the pope to help those most in need.

Regarding valid occasions for requesting the apostolic blessing, the almoner’s office establishes strict criteria. They are granted for sacraments such as baptism, first Communion, confirmation, marriage, ordination to the priesthood or permanent diaconate, and religious profession.

They are also available for significant anniversaries of these occasions and for birthdays marking decades or particularly significant ages (such as 18, 30, 75, or even 100 years). In some cases, such as wedding anniversaries or birthdays, the applicant is asked to provide a “declaration of suitability” attesting that the recipients are practicing Catholics.

Applications by regular mail, fax, or email are not accepted, and any requests made outside of authorized channels will be automatically rejected.

Obtaining an apostolic blessing is not only a symbolic gesture of communion with the successor of Peter but also direct support for the charitable works the pontiff carries out on behalf of the entire Church.

This story was first published by ACI Prensa, CNA’s Spanish-language news partner. It has been translated and adapted by CNA.

Note: You will not be paying for the blessing itself, but for the parchment and shipping fees. Do not buy religious items that have been blessed in advance prior to you purchasing it.

[lilith-hazel-mathematics]

Hi there, I’m not a mathematician, so idk if my question is silly, but why is it that integers in set theory are defined as a composition of all the previous integers instead of something simpler like for example just the set containing the previous integer? Is there something that makes the way we official define integers useful, or was it something like “this works, good enough”?

Hey, thanks for your question. What you're describing is actually Zermelo's construction of the integers, which uses the successor function S(n)={n}. You may recognize the name "Zermelo" from his greatest hit "Zermelo-Frankel set theory", the all-time most popular theory of sets, and arguably the de facto foundation of all modern mathematics. So, you are in good company in thinking that's the obvious implementation. However, the Von Neumann implementation (used in Hazel's "count to 100" challenge) is considered to be superior, which I think is for three main reasons.

The first and probably weakest reason is its convenience in defining the "<" relation. Under the Zermelo convention, you need to define "<" using the Recursion theorem, but it's much easier to prove Recursion when you already have "<" at your disposal. Having to prove the Recursion theorem without ever mentioning "<" is a pain in the ass. It's not terribly difficult to prove Recursion if you have access to the axiom of infinity, but it's way harder from a finitistic set theory, and that difficulty is compounded if you can't mention the "<" relation (I've done it and it's fucking annoying). I'm not a dirty finitist*, but I do have a deep interest in reverse mathematics, so these kinds of pragmatic concerns are important to me. Under the Von Neumann implementation, we simply have n<k if and only if n∈k, and the successor operation S(n)=n∪{n} isn't much more complicated. (*finitism is an unpopular but nonetheless respected mathematical philosophy, me calling it "dirty" is a joke.)

The second reason is its relationship to cardinality: as a set, a finite ordinal n contains exactly n elements, provided we use Von Neumann's implementation. For example, 0={} has 0 members, similarly 2={0,1} has 2 members, and so on. Besides being elegant for obvious subjective reasons, it's also pretty convenient in certain technical aspects. For example, there's an important set theoretic operation called set exponentiation, where Y^X denotes the set of all functions f mapping X→Y. In the finite case, it holds that |Y^X|=|Y|^|X|, hence the name and notation. This overlaps with the ordinary notation for the set of ordered pairs, X^2 = {(a,b) : a,b∈X}. This is compatible with the set exponentiation operation, but only if we use the convention 2={0,1}. That is, the ordered pair can be thought of as a function with domain {0,1}, in the sense that (a,b)[0]=a and similarly (a,b)[1]=b. This doesn't work under Zermelo's convention. A similar issue arises for triplets at 3, quadruplets at 4, and so on, essentially forcing the Von Neumann implementation all the way up, if we want this elegance. There are other technical roadblocks I'm sweeping under the rug (roadblock shaped like "a function is a set of ordered pairs"), but this answer is long enough already.

The third reason I'll say, and certainly the strongest, is its relationship to infinite ordinal numbers. Infinite ordinals are unbelievably important in set theory, for like a trillion reasons I could talk about for an entire decade, so it's pretty important to have some kind of implementation. The least infinite ordinal is named ω, which is the least nonzero ordinal obeying the property ∀(n<ω), n+1<ω. In other words, ω has no immediate predecessor. Under the Von Neumann implementation, we can simply say ω={n : n is a finite ordinal}, albeit the formal way to say "n is a finite ordinal" is a mouthful of logic. This extends to larger ordinals, in the sense that Von Neumann's convention allows us to easily construct ordinals of any infinite size. There's no good way to extend Zermelo's implementation to the infinite ordinals, so it's just not as good.

TL;DR Zermelo's convention works, but it's very slightly more inconvenient in almost every conceivable way. Nobody actually writes out Von Neumann ordinals by hand (except as a fun joke), so there are no downsides.... unless you don't have Axiom of Replacement, since then you have to use a completely different third convention which almost nobody knows about.

CoinMapAi - An All-round One-stop Service Platform for Web3

Fractal Bitcoin announced on the evening of September 6 that it will airdrop tokens to eligible UniSat and OKX wallet users, with a total of 1 million FB, accounting for 0.47% of the total token supply. Among them, UniSat and OKX wallets will each be allocated 500,000. The airdrop will automatically reach the user's address after the mainnet is launched.

**Project Background and Token Economics**

Fractal Bitcoin is a Bitcoin-based expansion solution that aims to increase transaction capacity by creating a recursive expansion layer on BTC while maintaining compatibility with the Bitcoin ecosystem. The project developed by UniSat has received investments from Binance, OKX Ventures, and others.

CoinMapAi - An All-round One-stop Service Platform for Web3-The total number of tokens is 210 million, of which 80% is allocated to the community and 20% to the team and contributors. The specific allocation is:

- POW mining: 50%

- Ecosystem Treasury: 15%

- Pre-sale: 5%

- Consultant: 5%

- Community funding: 10%

- Core Contributors: 15%

As can be seen from these allocations, Fractal has not reserved tokens specifically for airdrops, which may come from the ecosystem treasury or the community funding portion.

**AIRDROP RULES**

The airdrop rules are different for UniSat and OKX users:

CoinMapAi - An All-round One-stop Service Platform for Web3- **OKX users**: Need to hold more than 100 USD equivalent of BTC on September 1 and have traded Ordinals, Runes, Atomicals assets in the past 6 months, or be ranked in the top 5,000 in the OKX Web3 wallet BTC ecosystem activity. Eligible users will receive 6.6 basic FB rewards and 30 additional rewards.

- **UniSat users**: Based on the past 90 days of activity, including transaction volume, card holdings, and ranking, rewards range from 5 to 15 FB. The airdrop conditions are more complicated, including UniSat OG card, Prime card holders, and active testnet users.

**Community Feedback**

The number and conditions of the airdrops sparked some discontent:

CoinMapAi - An All-round One-stop Service Platform for Web3- The airdrop represented a low percentage of total supply (0.47%), which some community members considered to be too small an allocation.

- The rewards for loyal users and early testnet users are similar to those for regular users, causing dissatisfaction.

- High threshold requirements exclude new testnet users.

OTC PRICES

Currently, the price of FB in OTC trading is between $5-8, with a total market value of over $1 billion. Even though there are some complaints in the community, the price expectations for FB after it goes online are high. The airdrop rewards are concentrated between 10-40 coins, and at the current price, users may receive $60-240 in benefits.

**Summarize**

Fractal's airdrop strategy seems to be to allow more real users to experience its mainnet ecosystem, rather than simply distributing "pig trotters". This also reminds participants to pay attention to market trends after the mainnet is launched, avoid blindly following the trend, and ensure effective participation in ecosystem construction.

intro to Norwegian numbers!

So numbers in Norwegian are much like in english. They're not like Danish ("halvtress") or French ("quatre vingt quinze"), they follow a similar pattern to english.

This will be a glossary post.

number = booknorwegian = newnorwegian

or

number = booknorwegian and newnorwegian

(ei is a diphtong, use Google translate or YouTube or such for the pronunciation)

double consonant means the vowel before is short

I'll probably find a pronunciation guide for every Norwegian letter, but it follows rules pretty well. this exist idk how helpful it is: link NAOB. NAOB also always had the phonetic alphabet version of all booklanguage dictionary words.

For pronunciation you could also watch basic math videos such as basic multiplication.

1 = en = ein

2 = to

3 = tre

4 = fire

5 = fem

6 = seks

7 = syv (nb) = sju (nb&nn)

8 = åtte

9 = ni

10 = ti

11 = elleve

12 = tolv

13 = tretten

14 = fjorten

15 = femten

16 = seksten

17 = sytten

18 = atten

19 = nitten

(basically the number plus -ten, with maybe some old versions of the number often from Norse according to the dictionaries)

for 23 and 57 etc that's just tjuesyv etc.

20 = tjue

30 = tretti

40 = førti

50 = femti

60 = seksti

70 = sytti

80 = åtti

90 = nitti

for 100+ you say [[ett] hundrede] og [number under 100]. (ett = ordinal 1, hundrede≈hundred, og=and, førtisyv=47)

100 = hundre

every hundred after is just [cipher]-hundre

200 =to hundre

1000 = tusen

similar to hundred that's just [ordinal] tusen [[ordinal] hundred] og [any number under 100]. or just [[ordinal] tusen]

English million = million

English billion = milliard

English trillion = billion

English quadrillion= billiard

I don't know about everything above that, but at some point it changes to the regular system.

examples:

Jeg har ett tusen og tjuefire kroner -> I have a thousand and twenty four crowns. (literal)

(kronen (masc noun) is the Norwegian currency, known as NOK, other countries also call their currency that such as Denmark, it comes from the word crown)

Han er tretti år gammel -> he is twenty years old (literal)

Sunday with West Moonwingian - Counting

Amniši!

Let's begin with a funny thing about evolution. No more separate personal and non-personal systems! Now you only use the system that used to be non-personal. And it evolved into a mix of decimal and vigesimal, completely dropping the quinary bits.

Of course if you cast spells then you still use the magical system. And it's still decimal.

Now let's compare. On the left there will be the default system and on the right the magical system.

0 - Mem / Kaf

1 - Olin / San

2 - Tim / Son

3 - Sem / Ken

4 - Pom / Kim

5 - Sā / Šin

6 - Li / Kalin

7 - Ti / Pim

8 - Se / Pakin

9 - Tom / Takin

10 - Tin / Sin

11 - Tin olin / Sin san

12 - Tin tim / Sin son

13 - Tin sem / Sin ken

15 - Tin sā / Sin šin

20 - Toln / Son sin

30 - Toln tin / Ken sin

35 - Toln sem sā / Ken sin šin

40 - Tim toln / Kim sin

100 - Haln / Šam

10000 - Sāka / Šāk

22223 - Tim sāka toln tim haln toln sem / Son šāk son sin son šam son sin ken

To create the ordinal numbers you add the -āk suffix to basically turn the number into an adjective.

And here's some more words for today that are remnants of the old systems.

Tāsn - (noun/numeral) Dozen

Nom. - Tāsn (sing.), Tāsenjā (plur.)

Pos. - Tāsin (sing.), Tāsinjā (plur.)

Inst. - Tāsen (sing.), Tāsnenjā (plur.)

Trans. - Mtāsn (sing.), Emtāsenjā (plur.)

Tem - (noun) Couple

Nom. - Tem (sing.), Temjā (plur.)

Pos. - Tim (sing.), Timjā (plur.)

Obj. - Tem (sing.), Temjā (plur.)

Inst. - Temen (sing.), Temenjā (plur.)

Trans. - Emtem (sing.), Emtemjā (plur.)

Voc. - Temu (sing.), Temujā (plur.)

Temāk - (adjective) Romantic (used on its own can mean a romantic partner)

Olintemāk - (adjective) Homosexual (slang)

Jātemāk - (adjective) Polyromantic (falling out of use)

Jātem - (noun) Adulterer (slang, vulgar, pejorative)

Nom. - Jātem (sing.), Jātemjā (plur.)

Pos. - Jātim (sing.), Jātimjā (plur.)

Obj. - Jātem (sing.), Jātemjā (plur.)

Inst. - Jātemen (sing.), Jātemenjā (plur.)

Trans. - Emjātem (sing.), Emjātemjā (plur.)

Voc. - Jātemu (sing.), Jātemujā (plur)

And if you're interested how polyamory is doing with adultery claiming its word...

Poliamo - (noun) Polyamory

Nom. - Poliamo (sing.), Poliamojā (plur.)

Pos. - Poliami (sing.), Poliamīā (plur.)

Obj. - Poliam (sing.), Poliamejā (plur.)

Inst. - Poliamon (sing.), Poliamoenjā (plur.)

Trans. - Empoliamo (sing.), Empoliamojā (plur.)

Voc. - Poliamou (sing.), Poliamoujā (plur.)

That will be all for today!

[21st-century-minutiae]

Because there are uncountably infinite numbers and only a small number of symbols with which to write numbers, a system is employed to use a combination of numerical position and symbols to produce any arbitrary number. The "base" is how many different symbols are permitted. In the early twenty-first century, there are three different bases that are used primarily.

First is decimal, which uses the ten digits 0,1,2,3,4,5,6,7,8, and 9. Decimal is used in almost every circumstance.

Second is binary, which uses only the two digits 0 and 1. Or rather, it usually uses digital "on" and "off." This is used by computers.

Third is hexadecimal, which uses the sixteen digits, 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E, and F. It is used when humans are interacting with computer data, as it easily translates back and forth with binary (every digit in hexadecimal is 4 digits in binary), but takes up much less space when written out.

Arbitrary bases. Any positive whole number greater than 1 can somewhat easily be represented in a base. The problem is running out of symbols. Additionally, non whole numbers might be used to refer to fractal geometry. Technically speaking, any number can be converted into a base, but it would not be useful or reasonable. Base π can represent π with 10 and π^2 with 100, but would take an infinite amount of digits to render the number 4.

Regardless of the basis of the system, the number of digits will be represented with a 10. It is an inherently ambiguous statement. Conventionally, because of the overwhelming popularity of the decimal system, it can be assumed that the title of a basis, when describing it, will always be decimal. Thus Base 10 refers to decimal, Base 2 refers to binary, and so on. There is no law of mathematics asserting such, just societal convention.

Notably, the basis is used in representing numbers. It does not change math in any way whatsoever. Numbers still possess all the same properties no matter how they are rendered. The basis might make certain operations easier for humans to comprehend, but the results don't change.

Other, non-based representations exist in mathematics, such as von Neumann ordinals ({}, {{}}, {{}, {{}}}, {{}, {{}}, {{}, {{}}}}), and lambda calculus (λfx.x, λfx.f x, λfx.f (f x), λfx.f (f (f x))). However, these representation schemes are not useful in day to day life.

Oh, you're still using base 10? Haven't you heard? Nowadays everyone is using base 10

Cách phân biệt số thứ tự và số đếm trong tiếng Anh

Hầu hết mọi người thường bị nhầm lẫn giữa số thứ tự và số đếm trong tiếng Anh. Trong bài viết này, ELSA Speak giúp bạn phân biệt số thứ tự và số đếm trong tiếng Anh cũng như cách dùng chi tiết.

Số thứ tự trong tiếng Anh là gì?

Số thứ tự trong tiếng Anh là Ordinal number, được dùng để biểu thị vị trí hay thứ hạng của một người, một vật như: thứ nhất (First), thứ hai (Second), thứ ba (Third),…

Kiểm tra phát âm với bài tập sau:

Ví dụ: Five students participated in a contest. Out of them, three top winners were given medals and were ranked 1st, 2nd, and 3rd.

→ Có năm học sinh tham gia cuộc thi. Trong số đó, ba học sinh đứng đầu đã được trao huy chương và xếp hạng 1, 2 và 3.

Phân biệt số thứ tự và số đếm trong tiếng Anh

Nếu số thứ tự dùng để biểu thị vị trí, thứ hạng của con người, sự vật thì số đếm trong tiếng Anh được sử dụng để diễn tả số lượng của con người hay một sự vật nào đó.

Cách đọc và viết số thứ tự trong tiếng Anh

Khi viết số thứ tự trong tiếng Anh, bạn cần phân chia thành hai nhóm sau:
