Let's assume A = B...

A = B
A^2 = AB
A^2 - B^2 = AB - B^2
(A+B)(A-B) = B(A-B)
(A+B)(A-B)/(A-B) = B(A-B)/(A-B)
A+B = B
B+B = B
2B = B
2 = 1

well done amd_man and sam!! :) thats some quick thinking now!!!

(A+B)(A-B)/(A-B) = B(A-B)/(A-B)
here's the error mr.rocket: (a-b)/(a-b) = 0/0, which is not defined and hence all further steps are invalid! thus the final statement 2=1 is not true!!!

Good job, infra_red_dude...

2=1 *can* hold true, depending on what reality you live in =)

If you begin with this:

#include <stdreality.h>

Then yeah, it's false.

I couldn't agree with you any more than I already do...man, that is so true.

The human brain is an amazing thing, *when it's properly shifted into gear*!
