I think this is an important question deserving of this bulletin board.
Personally I believe they are distinct numbers and that people who think they are equal are just sloppy and incompetent!
What do you think /sci/?

Yes Anonymous you are correct in non-standard analysis 2.999... and 3 are distinct numbers with the difference being an element of the hyperreals.

Honestly, I hate it when people talk about this crap, and I think the guy that thought of this is an idiot. It's a lot easier just to work with 3 (or two, or one....).

algebra
let 2.9999...=x
then 10x=29.9999...
10x-x=9x
29.9999...-2.9999...=27
so 9x=27 and 27/9=3
