Mathematical proof 2=1
I found something very interesting, a mathematical proof showing that 2=1. It"s here:
Code:

And I think I already know where is the problem...

Re: Mathematical proof 2=1
a = b, so a - b = 0. And we all know what happens when you divide by 0, don't we?
"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."

Re: Mathematical proof 2=1
Good, you know where the problem lies 
Since a=b, a-b=0 and zero cannot be divided by the Left-hand side and the Right-hand side of an equation, no can zero can be cancelled on both the sides. This may result in absurd conclusions like 10=100, 500=1000 etc.
Only when the the two sides of an equation are divided by a non-zero entity, can they be equal.
Character is who you are when no one is looking.
