But the difference between 0.9999... and 1 is .1 not 0. 

 

At no point will you ever reach ....0001.

But I think it can, you just need:

0.9 + 0.1 = 1

I'm not sure what you mean, but I'll try to understand.

Let's change that 0.9 to 0.999 (infinite 9s). If the 1 were to remain 1, what would 0.1 have to change to? 

It would have to change to 0.000000.....
