Theorems that prove basic mathematics is wrong!
While i were checking some old mails and i found these hilarious mathematical proofs.
Theorem : 3=4
Proof:
Suppose:
a + b = c
This can also be written as:
4a – 3a + 4b – 3b = 4c – 3c
After reorganising:
4a + 4b – 4c = 3a + 3b – 3c
Take the constants out of the brackets:
4 * (a+b-c) = 3 * (a+b-c)
Remove the same term left and right:
4 = 3
Theorem : All numbers are equal to zero.
Proof: Suppose that a=b. Then
a = b
a^2 = ab
a^2 – b^2 = ab – b^2
(a + b)(a – b) = b(a – b)
a + b = b
a = 0

You start out by saying a + b = c, which means that a + b – c = 0.
So yeah, 4 * 0 = 3 * 0. Doesn’t prove that 4 = 3, just proves that 0 = 0.
Duh.
