How do you determine if two numbers are equal?

Iirc: x = y if and only if x - y = 0

If 0.9... - 1 = 0, then they are equal and vice versa.

Besides, the sum of the infinite series 9/(1-r) where r = 0.1 IS 1. Not about. Not increasing closer to one. It IS one. And that's all 0.9... is. An infinite series.
