#additional math

[snoopyscoop]

Hi

So I had Spanish yesterday and it went ok. It wasn't my best exam but it wasn't bad. It had a lot of repeating questions.

Today I when to school for 6hrs just doing math. I really need to improve for my grade for that last paper. Today I decided to go to my teachers lesson and it was actually helpful and I actually understood how we got to the answer.

I had planned to do biology but I am so tired, I may just watch a video. If I have more energy I would do one later.

Overall a productive day even though I only did math.

My totally serious guide to solving quadratic equations ✨

Sorry not sorry

I don't feel like writing rn, I feel like doing math🥰 so come

(Note = I used to take IGCSE Additional math and ext math soooo i hope this hepls if ur taking the same thing LOL)

(also pls don't unfollow i promise i wont be a full math blog 😔)

EXAMPLE =

x² + 4x + 4 = 0

ax² + bx + c

So as you can see there is a secret, hidden 1 in front of the x² so that will be our a value. For the b value you can get it in front of the x which is 4 and lastly the c is the number at the end with no variable so its 4.

TLDR; a = 1, b = 4, c = 4

So I usually make a big X thing and i put the product of a and c at the top and put the b value at the bottom. Like the pic above ig

So the product of a and c is 4 x 1 so it's 4 and then the b is just 4 so its 4.

THEN we gotta find 2 numbers that can be added to become 4 and mutliplied to become 4

SO it has to be like this (pretend the numbers are m and n)

m + n = 4

m × n = 4

So now we gotta do guess and check, I usually try to find the factors of the product, the one we have rn is 4 so

Factors of 4 are 1, 2 and 4

So let's try to find it! Let's try to check if 4 and 1 can.

1 + 4 = 5 ❌ <- doesn't add up to 4

2 + 2 = 4 ✅ <- adds up to 4

So now we just put it into the factors thing, Your answer should be (x+2)(x+2) or (x+2)²

BUT WAIT We're not done yet!

We gotta find x

So since it's (x+2) multiplied by (x+2) that means x + 2 = 0

and we just solve algebraically

x + 2 = 0

x = -2

So there's your answer

OR You could always use the

anyone know whether or not you need to take add maths (additional) to major in biology(or similar)?

[chamom1le-t3a]

school is so soooo mean to me (its been 2 days)

so have some tfp drawings cus WOW its been an eventful 24 hours..' [also pardon my fugly oc shes just a little guy ,, shes supposed to be an ex decepticon and somewhat a firefly (my dhmis moots will get the reference 😼)]

I drew three different doodles abt how I feel before my exam, after the first week and the end of my exam💔 (also persona reveal!!!!!!)

I don't think my hair could ever recover from such a loss 😭😭

jolie died 16 years before book 1, when she was 20 (so she'd be 36). as of stellarlune, she'd be around 38. she's 10 years older than alvar, and their parents were friends, which leads to the very distinct possibility that she babysat for the vackers (or at least, alvar and maybe fitz as a baby?)

The Batfamilys ages don’t make sense.

Or me dissecting the timeline of when the bats first met and why their ages are fucked up!

This is a lot of math that I did mentally while washing the dishes, I apologize if some of it is inaccurate, but I did the best I could.

(And yes, well all know their ages are fucked up, but I realized they’re a lot more fucked up then anyone first notices)

-I am ONLY doing the main family btw-

SO-

The very first Batfamily members to meet were Bruce and Alfred, it was kinda straightforward, Bruce was a baby Alfred was around the same age as his parents at early to mid 20’s.

List of the ages so far:

(I will be doing this every time)

Alfred Pennyworth: 24 ish

Bruce Wayne: 8



The second was Bruce and Dick (obviously), but this is kinda a odd one, but it’s still straightforward, Bryce went to The Flying Grayson’s show, he saw his parents die, and Y’know he decided right then and there he was going to be a foster parent. Good for him. But Dick is mentioned to be about like from 8 to 9 here. It’s more implied that he’s 8, because it’s supposed to be a parallel thing, to Bruce, with both of his parents dying in front of him at 8- so that the age I’m going to use for the beginning of this.

Bruce was supposed to be Batman for about 2-3 years before he took in Dick, so that’s what I’m going by to assume his age. (DC admit this man is mid fourths to early fifty’s , stop saying he’s early 40’s- he’s clearly not.) So he dropped out of college pretty early on, so I’d say like 19? Then he went on his trip around the world for a year or so and ended up at the League of Assassins to where he stayed for like- 2 to 4 years before he came back to Gotham. So I’m going to use the median of 2 and 4 and get that it was 3 years. (Same with the years before he took dick in, rounding out to 2.5) therefore Bruce was about- 23.5 ish when he took in Dick. And if you do some subtraction he’s only 17 years older than Dick, which works in a basic timeline of there being a couple references to Bruce being a ‘teen dad’.

Ages so far:

Alfred Pennyworth: 39 ish

Bruce Wayne: 23.5 ish

Richard Grayson: 8

Say what you want, but Barbara is apart of the batfam- I know some people like to say she’s a bit like Huntress and isn’t- but to me she is. She is the original Batgirl, and is very much apart of the Batfamily to me.

So she’s older than Dick, I’m not sure how much older, but I’m her first appearance (when she wasn’t being shipped with Bruce) she was about 2 years older than him (?- I think I can’t find anything on google with any confirmation and I don’t have old comics on hand rn).

But her first appearance was when Robin (dick) was about 12-13, I’m just gonna put 12.5 for the sake of putting 12.5.

Meaning her first appearance was when she was about 14 ish. And was about- 6 years later.

Ages so far:

Alfred Pennyworth: 45 ish

Bruce Wayne: 29.5 ish

Richard Grayson: 12.5

Barbara Gordon: 14

The next is Bruce meeting Jason. To figure out the ages here we first need to figure out the amount of time between him meeting Dick and meeting Jason. So let’s talk about the age gap between Jason and Dick.

It’s believed that their age gap is from 5-8 years, so let’s just go to the middle and say it’s 6.5 years. Jason is supposed to be 12 when Bruce first meets him, when he trying to tirejack the Batmobile. So if we add 6.5 to 12, Dick is about 18, meaning it’s been around 10 or so years. Which actually lines up believe it or not. (The old writers could actually stick to a timeline unlike the newer ones.)

But I can’t find any older comics to figure out if Bruce took Jason in right then and there, or he saw him again about a year later and took him in then. So let’s just say Jason is 12.5 when Bruce takes him in.

Ages so Far:

Alfred Pennyworth: 49 ish

Bruce Wayne: 33 ish

Richard Grayson: 18

Barbara Gordon: 20 (This also would be post paralysis as she was 19 when it happened)

Jason Todd: 12.5

When Tim comes into the family is when it gets confusing. We’re not even starting with the first time he met the family, we’re starting back with Flying Grayson’s Show.

So, Dick as we’ve established is 8. Jason is about 6.5 years younger than him. Making Jason about 1.5 when the show happens, but a very often mentioned age gap in all of the batkids- is between Tim and Jason. As Tim was 13 when Jason died. Jason was 16. Tim was 16 when Jason came back. And Jason was 19.

It’s a three year gap, therefore, Tim couldn’t have attended that show. But I don’t think anyone did the math there, meaning that’s where the first timeline inconsistency starts to occur. But it’s okay, because in a few versions Dick was said to be about 11, meaning Jason would’ve been 4ish and Tim about a year old. Most babies don’t remember stuff that happens in this time, but it is possible, so I’ll just scratch it up to multiple different world and the writers forgetting.

But when Tim does finally meet the family he is 13, as it is right after Jason’s death when he is 16, he becomes Robin because Dick basically hands him the suit, when Tim tells him Batman needs a new Robin, and yeah.

So a three year gap. Timeline a bit messed up, but it can’t get that much worse, right? (Wrong.)

Ages so far:

Alfred Pennyworth: 52 ish

Bruce Wayne: 36ish

Richard Grayson: 21

Barbara Gordon: 23

Jason Todd (assumed dead): 16

Tim Drake: 13

So the next person is always a bit confusing, some think it’s Steph, others think it’s Cass, but Cass was batgirl first, however Steph was Spoiler first- They kinda started at about the same time- so I’ll just smush em in together.

So Cass is said to be older than Jason by only months. And they both come in at about a year of Tim being Robin, putting Cass at 17, which also doesn’t line up with the timeline, as Bruce says she is 16 (I can’t find the panel but it’s in one of he 2000’s runs I believe I can’t confirm exactly) but it’s close in age, so I’ll let it go.

Steph is said to be both the same age as Tim, but other times older, so I’m going to place her at 15 here. A year older than Tim since it’s only been a year since Tim started as Robin.

Ages so far:

Alfred Pennyworth: 53 ish

Bruce Wayne: 37 ish

Richard Grayson: 22

Barbara Gordon: 24

Jason Todd (assumed dead at 16): 17

Tim Drake: 14

Cassandra Cain: 17

Stephanie Brown: 15

So the next is Damian- obviously.

So Damian is 10 when he comes, it’s mentioned multiple times. Yay an easy to confirm age, we love it!

Jason also comes back.

However Tim is mentioned to be 16 here, so we can easily just get everyone’s ages from doing the math from their ages previously. Most people when calculating their ages skip Steph and Cass and say it’s a six year gap between him and Tim, which does line up, but without Steph an Cass there it still fucks with the timeline a bit.

Ages so far:

Alfred Pennyworth: 56 ish

Bruce Wayne: 40 ish

Richard Grayson: 25

Barbara Gordon: 27

Jason Todd (now alive again): 19

Tim Drake: 16

Cassandra Cain: 19

Stephanie Brown: 17

Damian Wayne: 10

Now we’re on Duke. Which is where it gets all fucked up.

So Google says Duke is four years older than Damian, and his first appearance is when Damian is 11 or 12iah, making Duke about 15 or 16, in his first appearance. But also in this time, DC stopped aging Tim all together, they supposedly aged Cass down, and Steph closer to Jason’s age. Which fucks the whole timeline up, but let’s not get into that.

We can just go from Damian’s age to get the rest, meaning it was a two or so year gap from Damian arriving to when Duke first started in the ‘I Am Robin’ movement and soon after became Signal

Ages so far:

Alfred Pennyworth: 58 ish

Bruce Wayne: 42 ish

Richard Grayson: 27

Barbara Gordon: 29

Jason Todd: 21

Tim Drake: 18

Cassandra Cain: 21

Stephanie Brown: 19

Damian Wayne: 12

Duke Thomas: 16

This is what their ages would’ve been if they didn’t continue to age Damian up and no one else, so here’s what ages they SHOULD be. (This is for you Tim.)

Since Damian is 14-15 in comics currently- everyone should be a bit older too- but DC refuses to age them up. (I’m going to use 15 just because, making it a THREE year difference.)

Ages they should be:

Alfred Pennyworth: 61 ish (I don’t care if he’s dead)

Bruce Wayne: 45 ish

Richard Grayson: 30

Barbara Gordon: 32

Jason Todd: 24

Tim Drake: 21

Cassandra Cain: 24

Stephanie Brown: 22

Damian Wayne: 15

Duke Thomas: 19

Someone needs to ask Duke how college is going, or ask Tim how it feels to drink. Maybe someone should ask Dick how a mid-life crisis feels, when you’re actually close to the mid-life age. (He’s had them before, but now he’s actually closer to the midlife age.) Have someone ask Bruce how it feels to be in his 40’s and still get called hot, to get called ‘beekeeper age’ by people- and still get voted hottest man of the year, yearly.

There’s so many untapped humor opportunities that come with their chronologically accurate ages. But DC is full of pussies.

you're disgusting.

i was going to be flippant about this until i saw you're seventeen, so im gonna be serious for a minute.

if you actually think i did all the stuff i've been accused of in the call-out posts that you reblogged, you're an idiot. you're a minor going after someone you think is some kind of invincible super predator with a whole mafia of supporters to bully my accusers into silence so you cone right up and do a little schoolyard taunt? that's ridiculous. get a hobby that doesn't involve direct interpersonal contact with monsters. you're not joan of arc. you're not speaking truth to power. you're lashing out in deeply stupid ways that are, at best, going to be really embarrassing to remember in ten years. and at worst will ruin your life.

and if you don't actually believe the call-out posts, which, hey, you shouldn't because they're bullshit, you're just one more asshole giving some random dude a hard time. like, i don't actually prey on anyone and i'm not actually a pedophile and exactly zero of my fanfictions actually conclude 'rape is great, go rape people'. my main crime is im very annoying, which unfortunately for tumblr users does not confer the death penalty.

so given all that, you're a jackass, and need a better hobby than being mad at whoever you're told.

merry shitscram, grow up and don't do this to anyone else.

Happy (belated) birthday @shepscapades!!!!! This fic did not exist yesterday but it sure does now! Another dbhc au docsuma set in hermitcraft season 10, during Doc’s building of the Big Wood hourglass (and after “Anyways. What?”)

word count: 1114 words

“Whoa.”

Xisuma lets his boots scuff against the grass, folding his elytra away without taking his eyes off the towering hourglass before him. An hourglass that he is sure did not exist, well, yesterday. 

He checks his communicator again, still showing Cleo’s message from last night. Just a simple, “Not urgent, but you should head by the shopping district.”

The “not urgent” part of the message had been what allowed Xisuma to rest until morning before popping by. It seems, though, that someone else did not do the same.

Based on the untouched bed covered in soot beside a double shelf of furnaces, Xisuma thinks he knows exactly why he was called. Even as he starts looking around for a familiar lab coat, he resigns himself to yet another shred of fodder that will soon be added to Cleo’s arsenal of stories.

“Doc?” Xisuma’s voice echoes around the base of the hourglass. A quick squint through the glass is enough to deem it empty as well. Finally, Xisuma tilts his head up, towards the very top of the hourglass. No movement that can be seen from down here, but it would be a reasonable place to check. 

Sure enough, a quick elytra trip later and Xisuma touches down on the top of the hourglass to find Doc standing right in the middle of his goat-shaped glass panels. 

“Doc, hey!” 

His greeting seems to startle the other, though Doc has never been one to show it. His body turns to face him without so much as a flinch, his shock only betrayed by the second of hesitation it takes for Doc’s expression to curl into an easy smile.

“Xisuma.” A nod in greeting, and then Doc seems to really come back to himself, looking around with his LED ring blinking a brighter blue, if only for a moment. 

“You built all this up in a day?” When Xisuma speaks, Doc’s eyes snap back to him. Again, it takes a moment before Doc responds. Coupled with his slumped shoulders and the way he almost seems to sway in place, his entire form screams exhaustion.

His voice masks it well, though that could just be the lingering passion that has kept him going for this long. 

“Yeah! It’s going to be the biggest shop in the shopping district. All the wood will be sold here. That is, uh, once all the other permit holders agree to sell it here. But they will!”

“Right.” Despite his concern, Xisuma laughs. It is usually Xisuma who has to be pushed and shoved into taking a break, not the other way around. Oh, how the tables have turned.

Xisuma steps closer, brushing off a mixture of soot and sand from Doc’s shoulder. As usual, Doc eyes Xisuma quietly, making no move to push or pull away. 

“When’s the last time you slept?” This close, Xisuma can see the flicker of yellow in the whirring of blue. 

“Uh,” Doc manages, after a long moment. “Uhm. I slept.”

Xisuma hums. He must not manage to keep the skepticism out of his voice, because Doc doubles down. 

“I did! I went into rest cycles of ten to twenty minutes every three hours. That’s enough for functionality.”

“Barely enough,” Xisuma retorts. His hand finds Doc’s shoulder again, resting there. “You’re supposed to have longer rest cycles than that, Doc.”

Doc scoffs in reply, though he leans some of his weight into Xisuma’s hand, a greater tell than anything else.

“Tell you what.” The bed at the base of the hourglass is hardly an ideal place for resting. Thankfully, there’s better places nearby. “Come over to the lab. I’ll show you the new systems I installed after you sleep for the day.”

The words catch Doc’s attention, at least. “New systems? I don’t remember an update.” 

“Just a little testing here and there.” A squeeze to Doc’s shoulder halts his next words. “Nuh-uh! I’ll tell you after you get some shut-eye.”

Doc huffs, but does quieten after that. Xisuma leads the way back to the lab, keeping track of the sounds of Doc’s rockets behind him. While Doc is not so exhausted as to crash while flying, Xisuma’s mind still niggles with worry.

By the time they land, it seems the long hours of work have properly caught up to Doc. Xisuma turns around just in time to spot Doc fumble his landing, tripping over nothing but his own feet. He manages to remain upright, if only because Xisuma braces his hands under his arms in time. 

“Enough for functionality, you say?”

Doc grumbles, knocking a fist against Xisuma’s chestplate. “Shush.”

Xisuma manages to stifle his laugh as he leads Doc into the lab. The hand still lingering on Doc’s arm is entirely unnecessary now that Doc has regained his balance, but neither of them comment on it. 

Owing to their horrible work ethics, one of the first places Xisuma tends to build at his labs is a small bedroom. It feels refreshing to be the one ushering someone else into the room, instead of being the one to trail behind.

“There you go.” Xisuma tugs Doc into sitting on the edge of the bed. His elytra digs into the bedding behind him, Doc turning to blink at it like he just remembered it there. 

Faster than Doc, a rarity from the beginning, Xisuma slips the elytra off Doc’s shoulders, folding it away before Doc can protest the coddling. Not that it is coddling, really. He just wants Doc to be comfortable, is all.

The “yeah, right” that hums in the back of his head sounds very much like Cleo.

By the time Xisuma looks up from storing the elytra, along with some golden carrots, in the bedside chest, Doc has managed to shift himself flat on his back, lying over the duvet instead of under it. The sigh Xisuma lets out is fond, an emotion that he hopes his helmet hides.

“At least pull the covers over yourself.” 

In reply, Doc grunts and waves his hand dismissively. Not in a rest cycle just yet, but very close to one.

Well, so much for not coddling. Somehow, Xisuma manages to pull out the duvet and drape it over Doc. By the time Xisuma finishes his fussing, Doc has gone still, his blue ring of light dimming in rest.

Xisuma risks a final brush of his fingers to Doc’s shoulder, the metal hidden under the duvet. “Sleep well, Doc.” 

No movement, to his relief. Quietly, Xisuma backs out of the room, shuts the door gently, then heads for the labs. He should pull up the new systems again, just to refresh himself on what they can do.

Haymitch was a mentor for 23 years before the 74th games, that’s 46 tributes he lost. If they’d played by the rules and only brought Katniss home then that would have been 47.

Same number of tributes killed in his own arena.

There’s something about him being spared matching that number, especially if you factor in Woodbine and Louella, who would have brought the total to 49, the same number it likely would have reached if the third Quell went as usual.
