Proof Positive

For those of you who are mathematically-inclined, here is a simple proof to show that "0.999... = 1" (link here): (1) Let x = 0.999..., (2) then 10x = 9.999..., (3) now subtract x from both sides, (4) we get 9x = 9, (5) which reduces to x = 1, (6) thus, x = 0.999... = 1. Hmm. Intriguing. Yes, it's been a slow morning.
