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.
