Fascinating what "results" you can get when you doing
nothing but manipulating symbols (without regard to
meaning). But where did x come from?

Also, I'm not convinced that the first line is correct
(-1/0 = 1/-0 = 1/0). If 1/0 is taken to be something
positive, or at least greater than zero (1/0 > 0), then
surely -(1/0) < 0?
