The transfinite ordinals are ordinals, not "numbers"; and the Alephs are cardinals, not necessarily numbers either. If by "Cantor set" you mean that set of "trinary numbers between 0 and 1 which don't contain the digit 1" then that's a set (of cardinality 2^Aleph0 and measure 0) and not a number either. > Also, the fact that you can have positive and negative zero... In what branch of mathematics? I've never heard of it. imc
