People that are saying in chats are just trying to tell you that they only have a half brain cell left.

Person 1: Hey, wanna play something?

Person 2: (1/2)

Person1: I'm very sorry to hear that my friend.

Person 2: (1/2)

The person before made a mistake in their proof.

1. x = y

2. xy = y^2

3. xy - x^2 = y^2 - x^2

4. x(y - x) = (y + x)(y - x)

So far so good.

4.5. x = (y + x)(y - x)/(y - x) is what they did to get to step 5, which says:

5. x = y + x

This is wrong though. since x = y, y -x = 0, and so you can't divide by y - x.

1. x = y

2. xy = y^2

3. xy - x^2 = y^2 - x^2

4. x(y - x) = (y + x)(y - x)

So far so good.

The equation of choice among math paradoxers and recreational mathematicians, who unspokenly derive much satisfaction in exposing students’ fallacious or illogical reasoning that leads to the contradictory result.

Be it due to division by zero or squaring (or square rooting) both sides of an equation, few students wouldn’t want to know why “1 = 2” is logically plausible.
