Consider the following math example:
x2 – x2 = x2 – x2 *Note: the 2s on this line are all superscript
x (x-x) = (x-x)(x-x)
x = 2x
1 = 2
I remember a few months ago I read some article that gave an explanation for this conundrum (it was some link from yahoo.com), but now I cannot find that article. Can someone find that article? Or, at the very least, can someone else explain why this does not violate mathematics?
