[q]Of course, writing a 9 at the end of an infinite string of nines makes no sense, and neither does the equation x + 1 = x.[/q]
x + 1 = x is true for { x | x є ∞ } and only that. x + 1 != x for { x | x є R }
and as for the concept of 999... , would that just be ∞ ? Or would it be the lim (x2) x -> ∞ ?
