Proof that 2 = 1
Start with: X = Y
multiply both sides by X: X*X = X*Y
subtract Y^2 from both sides: X^2 - Y^2 = X*Y - Y^2
do some factoring: (X+Y)*(X-Y) = Y*(X-Y)
divide both sides by (X-Y): (X+Y) = Y
substitute Y for X: (Y+Y) = Y
divide by Y and simplify: 2 = 1
There you have it, a mathematical proof that two is equal to one!

X=Y
=>X-Y=0
So you are actually trying to divide by zero which is not permitted in this context (an undefined operation).

Yes, Anon. I am dividing by zero, it's funnier that way.
