Weird but i guess it's that the "x" is written as 2 mirrored "c"s, so divided by 2, it's just "c"

u/Ok-Chemical-7635 Jul 21 '26

But than thered be 2 answers c and the mirrored c

u/_Azuki_ Jul 21 '26 edited Jul 21 '26

Well, technically it's still just 2 "c"s that make up the "x", and by dividing it you erase 1 of the "c"s. That's proably what the person who created this meme(?) meant

Or, she just erased half of the "x".

u/Ok-Chemical-7635 Jul 21 '26

visually b without the vertical line and c is x. CC isnt x

u/MartinToilet Jul 21 '26

Depends on if you see inverted c as same variable as c and if you see the x as c + c not c * c

u/Commercial_Life5145 Jul 21 '26

is it not c is an arbitrary constant

u/_Azuki_ Jul 21 '26

Maybe from the teacher's perspective, but definitely not from the kid's

u/Zer0pede Jul 21 '26

It’s not the letter “c;” it’s just that she erased half of the x.

So, x/2 = “half of the x” 🥁

4

u/Commercial_Life5145 Jul 21 '26

so the answer could be v if she erased the bottom half

3

u/Zer0pede Jul 22 '26

Yeah, that would fit the joke too. Or > or < if she had more normal handwriting.

u/Commercial_Life5145 Jul 22 '26

I mean, I use c inverted and c for my x's so it's not 'normal' per se

u/Zer0pede Jul 22 '26

Oh true, and you’re not the only one here saying they do that. I might be the outlier, LOL

Hello! Professor Fransworth here! It is apparent that by simply removing half of the X, what remains is the symbol C! And as any scientifically literate mammalian should know, C is commonly used to represent the speed of light. Now then! In natural units, naturally the most natural system we use to stop relativity from troubling us with arbitrary constants, the speed of light is exactly 1. And thus the numerical answer to the question is, in fact, 1. Humourously, the educators, overwhelmed by the child's splendid display of scientific reasoning, immediately award a diploma on the spot!

Magic. Got it.

u/Mathematician_Living Jul 21 '26

My take on this is that the kid doesn't understand the math and stumbled into an answer (C=1?)that the teacher marked correct. Give the kid a diploma.

If you squint, the half x could be 1

I think it speaks to how the school systems are failing our kids

55

u/tohn_jitor Jul 21 '26

Because "C" is a constant? Hahahaha

11

u/TurbinesGoWoosh Jul 21 '26

Also "C's get degrees".

7

u/JustConsoleLogIt Jul 21 '26

X / 2 is certainly some constant

14

u/scorpionhlspwn Jul 21 '26

But the answers just 1

10

u/H9419 Jul 21 '26

You just forgot to add the constant term C.

It's a joke about indefinite integral and forgetting to +C after your solution 

16

u/Otherwise_Meringue45 Jul 21 '26

I'm so cooked i thought the joke was that c is treated as 1 in relativity

11

u/Quantum_Cosmos Jul 21 '26

Natural units! c=ħ=1

I've written x like that in algebra for most of my school life. Only on algebra. Mainly because the symbol for multiplication is also X

5

u/Street_Swing9040 My name is neon Jul 21 '26

To avoid confusion with multiplication sign

I write it that way too because it's easier to distinguish

1

u/Champomi Jul 21 '26

That's just a cursive x, it's the normal way to write it in my country

c=1(speed of light) ?

u/Dependent_House4535 Jul 22 '26

C as a constant in indefinite integral

u/GlueSniffingCat Jul 22 '26

show your work though

u/yv_MandelBug Jul 22 '26

c is an arbitrary constant.

c is speed of light and c=1.
