Theorem: 4 = 5

Proof:

-20 = -20
16 - 36 = 25 - 45
4^2 - 9*4 = 5^2 - 9*5
4^2 - 9*4 + 81/4 = 5^2 - 9*5 + 81/4

Since (a-b)^2 = a^2 + b^2 - 2ab


(4 - 9/2)^2 = (5 - 9/2)^2

Taking under root of both sides

4 - 9/2 = 5 - 9/2
4 = 5

:D where is the catch?

Definitly This is not my research, I wish I would be that intellegent

Nice trick used.. 8)
I hope someone who read match in Intermediate would be able to find the trick.

Nice theorem to impress 99% of folks. :mrgreen:

Good one!!

good
