So, how do we know that 3*.3333333... = .99999.....?
This is not a proof, and seems to get back to Mark's original point about arithmetic with infinite decimals.
An unrelated point...I use the density argument to try to persuade students that .999...=1. If they're different, name the real between 'em.
