That is, it looks sound until you realize it's complete garbage.
Here's the proof in question:
WOW! AMAZING! A mathematical fallacy, surely the universe is torn asunder or at the very least flipped turn-ways.
No. Sorry. Here's the problem with this proof:
Since a=b, a-b=0, and you CAN'T DIVIDE BY (a-b) TO CANCEL IT BECAUSE IT'S ZERO AND YOU CAN'T DIVIDE BY ZERO.
QED.
Proof disproven. Stop showing me this as if it is a novelty; it's troll math.
Similar case of troll math that I found while looking up the first case:
This one seems sound and then takes a huge leap off the deep end. I actually had to whip out my calculator to figure out just what was wrong with this one because it looks sound, and the problem isn't where I was expecting it to be.
When you square something, it's going to be positive. When you take the square root, you're going to get two answers: a positive answer and a negative answer. This proof takes the negative answer for one and the positive answer for the other one and says they're equal. They're not. This should actually read -4+9/2 = 5-9/2, which is true. Unfortunately for this "proof," it means the rest of the problem isn't anything particularly mind-blowing. If you cancel everything out, you'll get 0=0.
Guys, if you're going to try to disprove math can you at least do it using real logic?
Oh wait. You can't. Because math is pure logic.
Q E fucking D.
