Last night I dreamed that one of the main plot points in Autumn Troupe’s story was Taichi actually just. straight-up dying
so that was fun
Taichi: My name is Taichi with a B and I’ve been afraid of insects my whole li-
Yuki: Stop, stop, stop.
Taichi: Hm?
Yuki: Where’s the B?
Taichi: THERE’S A BEE?!?!
miku didn’t invent Minecraft for me to have to put up with my tumblr app notifications bar bugging out and only showing me my empty direct messages inbox
Part 1
Izumi: Show me what you have!
Sakoda: A backhoe!
Izumi: NO!
Izumi: I mean, I got Azuma to spill his whole backstory in, like, two sentences.
Azuma: I refuse to be held accountable for this. You caught me in a moment where I was emotionally vulerable and craving intimacy.
Homare: ...are you ever not either of those things?
“Winter Troupe!.. I don’t actually have a job for you. Uh... sit around and be sad about something, you’re good at that.”
-Izumi
Hisoka: I can expla-
Izumi: You’re a secret agent. You’re a secret agent! I can’t believe this! What, is anyone else here living a bizarre double life?
Izumi: ...
Izumi: Put your hand down, Citron.
yuki is mvp
did u see my reblog of ur math post :0
Oh sorry! I didn't sjfjsj I deleted it a while after so I didn't get any notifs for it ;;
Idk how you were supposed to do that with systems of equations :O if you ever get that explained send the work my way I wanna see that
Izumi: Well- Azuma, what do you normally do when we’re gone?
Azuma: ...wait for you to come back.
my first a3! piece of my two favs :>

Can anyone help me solve this djfjsfks
If u cant read it the pic says
A parade is made up of 100 rows of people. It contains a first row with a one yr old, followed by a second row with two two yr olds, followed by a third row with three three yr olds and so on until the 100th row contains 100 100 yr olds
A) write a function(equation) and use it to determine how many ppl are in the parade
B) write a function(equation) and use it to determine the sum of the ages of all the ppl in the parade
Repayment for the wonderful translation link.
Part A is an arithmetic series! This means it’s a series of numbers where each value has a common difference- in this case, each term is one more than the last (1, 2, 3, 4, etc...). To find the sum of people in this parade with n rows, you use the arithmetic series sum formula, which looks like this:
n/2(2a1+(n-1)d)
a1 is the first term in the series: 1.
n is the number of terms in the series: 100.
d is the common difference between terms: 1.
So, plugging in numbers, we get...
100/2 • ( (2•1) + ( (100-1) • 1 ) )
50 • (2 + 99)
50 • 101
5,050 people in the parade!
Part B, meanwhile, is ‘sum of the first n squares’. (I had to learn this one new myself- I think it’s usually an advanced topic, since all I can find is people agonizing on how the equation was found.)
To add all the ages of the people in the parade row by row, you would probably do something similar to:
1 + 2 + 2 + 3 + 3 + 3...
or
1^2 + 2^2 + 3^2...
Multiplying every number by itself, then adding them all together. The formula for this is:
(n(n+1)(2n+1))/6
So, plugging in 100, you get...
( 100 • (100 + 1) • ( (2 • 100) + 1) ) / 6
(100•101•201)/6
2,030,100 / 6
338,350 is your answer!
hope this helped :3
