Tell me I'm wrong. TELL ME I'M WRONG.

2 + 2 = 4
2 x 2 = 4
3 + 3 = 6
Therefore 3 x 3 = 6

Relevant xkcd

x^3=125
x^3=(1+2)5
x^3=35
x=5
- x⁴=625
  x⁴=(6-2)5
  x⁴=45
  x=5
  
  I love Facebook math.

Is she setting up a silencer?
- She's taking it off to send a message to the rest of the class
- She is about to silence someone, that's for sure.

TELL ME I'M WRONG.
you're wrong. x = -5 is also a solution lmao
- Is it though? Doesn't it have to be (x)² then? Because -5² = -25 ?
  
  No, because what you are doing isn't x^{2 with x=-5. It is -x}2 with x=5.
  
  If you multiply a negative number with a negative number you get a positive number.
  Edit: Sorry, misread your comment, I clearly didn't get enough sleep. In printed mathematics, the unary minus sign has a lower precedence than the exponent, but in programming, it's the other way around, with the unary minus being applied first. So your right in printed mathematics, but wrong in programming.

X^2=625
X=65
Holy shit it works
- X=25 actually. We were wrong about the pattern; obviously the square cancels with the first digit

Sometimes it be like that. Somes it don't.

Okay, now try it with x²=16!
- x^2=16!
  x^2=20922789888000
  x^2=20922789888000
  x=922789888000
- x = 5 in this case as well, unless you can post a mathematical proof it is not.
  
  Plus we already found x once in the meme.
- X= D6. Simple.

the left 2 is smaller than the right 2, so the answer is actually

x = (size) 5
But the size is represented by a whitespace symbol. Still, that's gonna propagate and totally flummox a future calculation on that x

This reminds me of a maths test I had when we had just been taught to calculate how many m2 an area was.
I seem to recall seeing an example of the formula where the answer was 2 m2, ok, looking at the test there was a question that had answer to be 6 m2, but me trying to be clever, though that the 2 in m2 represented the value of the answer, wrote 6 m6.
I failed that test....
- That's why you have to do more than one (1) homework
- this is some galaxy brain move.

try it when X equals 3
- X=3
  
  It works!

Dammit! That's genius!

Me IRL solving primitives sometimes

Mario Maker players all know x=9
