Here ya go! As bigdave says though, this is a false proof as you're dividing both sides of the equation by 0 (since a-b=0). Now can we talk about the game?!
a = 1
b = 1
a = b
a2 = b2
a2 - b2 = 0
(a-b)(a+b) = 0
(a-b)(a+b)/(a-b) = 0/(a-b)
1(a+b) = 0
(a+b) = 0
1 + 1 = 0
2 = 0
1 = 0
1 + 1 = 1
as you say its false proof which your right there, using representatives for the numbers etc which is not the issue here.
back in baby school if you answered 2+2=5 you either get laughed at or moved to special aid classes.
i for one will only teach my 4 year old 2+2 = 4 and leave it at that.
