What about it? Everyone knows
2 = 1. Here;
Assume that
x and
y are the same number. For example;
x = 1 and also
y = 1. So I could write down
x = y and it'd be valid.
So now I'm really writing it, LOL;
x = y
Since x and y are the same crap, I can represent the above equation as;
x2 = xy (as in X squared equals X times Y)
Now, I sustract
y2 from both sides of the equation.
x2 - y2 = xy - y2
Everyone here who ever learned algebra will agree that x2 -
y2 factors as (
x + y)(
x - y). And we can also factor
xy - y2 like this:
(x + y)(x - y) = y(x - y)
All correct? Absolutely! Now, we have (
x - y) on each side, it's the common term. We can devide each side by (
x - y) and simplify the equation. That leaves us;
x + y = y
I've said x and y are both 1, yeah? So;
1 + 1 = 1
2 = 1
Ta ta!
