.999... =/= 1
It only approximately equals to it. It would be viewed the same way as a number approaches a limit, but never actually touching it. Calculus stuffs.
edit: "On the number line, there is no real number between 0.99999..... and 1. If there is no real number between any two numbers, then those two numbers are of the same value. There is no number higher than 0.9999... and lower than 1, therefore they are of the same value."
I should also say that for this part, it would be better to look at it as a line on a graph rather than a point on a number line.
