0.999999... = 1?

What the fuck. Why is that true. They got different numbers in them.

>>133

Following that logic
1 = .999...
and
.999...9 = .999...8

therefore 1 = .999...8
But the number .999...9 is between 1 and .999...8
So 1 can't = .999...8
But if A = B and B = C, but A does not = C, then there has to be a problem with the logic system, no?
