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..

Why did the vector cross the road?
It wanted to be normal.

Disturbing.


A logarithm is just a misspelled algorithm.
