A + B = A?
Hey, check this out:
If A=B
let A = 3 and B = 3
B^2=AB
so A^2 - B^2 = A^2 - AB
(A+B)(A-B)=A(A-B)
A+B = A ??
...I know why this is wrong.. but I think it's pretty cool..

Re: A + B = A?
Yes, I've seen that one before. Doesn't stop it from being cool, though.
Here's why it doesn't work:
Why did the vector cross the road?
It wanted to be normal.
