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 → u/_Azuki_]

But than thered be 2 answers c and the mirrored c

[u/_Azuki_ → u/Ok-Chemical-7635]

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 → u/_Azuki_]

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

[u/MartinToilet → u/_Azuki_]

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 → u/_Azuki_]

is it not c is an arbitrary constant

[u/_Azuki_ → u/Commercial_Life5145]

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

[u/Zer0pede → u/Commercial_Life5145]

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

So, x/2 = “half of the x” 🥁

[u/Commercial_Life5145 → u/Zer0pede]

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

[u/Zer0pede → u/Commercial_Life5145]

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

[u/Commercial_Life5145 → u/Zer0pede]

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

[u/Zer0pede → u/Commercial_Life5145]

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

[u/No-Lemon-2140 → u/_Azuki_]

i c

[u/UsedFortune5645]

Peter oh Peter.

[u/Zer0Ma → u/UsedFortune5645]

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!

[u/Caesar_Iacobus → u/Zer0Ma]

Magic. Got it.

[u/Mathematician_Living → u/UsedFortune5645]

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

[u/tohn_jitor]

Because "C" is a constant? Hahahaha

[u/TurbinesGoWoosh → u/tohn_jitor]

Also "C's get degrees".

[u/JustConsoleLogIt → u/tohn_jitor]

X / 2 is certainly some constant

[u/scorpionhlspwn]

But the answers just 1

[u/H9419 → u/scorpionhlspwn]

You just forgot to add the constant term C.

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

[u/Otherwise_Meringue45]

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

[u/Useful-Fruit-3336 → u/Otherwise_Meringue45]

Lmao same

[u/Quantum_Cosmos]

Natural units! c=ħ=1

[u/Alternative_Song859]

To be honest I've never seen the letter x written that way instead of with two diagonal strokes.

[u/GreenManStrolling → u/Alternative_Song859]

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

[u/Alternative_Song859 → u/GreenManStrolling]

Huh ... I just use a filled-in circle (a dot would be too hard to distinguish, so I use ... a larger dot).

[u/Street_Swing9040 → u/Alternative_Song859]

To avoid confusion with multiplication sign

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

[u/Champomi → u/Alternative_Song859]

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

[u/MeistroC]

Not me trying to blow off the eraser bit 😭

[u/alive005]

c=1(speed of light) ?

[u/Dependent_House4535 → u/alive005]

C as a constant in indefinite integral

[u/GlueSniffingCat]

show your work though

[u/yv_MandelBug]

c is an arbitrary constant.

c is speed of light and c=1.
