O.K.... was doing some doodling and figured I'd crunch some numbers just for the hell of it :P what can i say i'm bored :)
well while i was messing around i discovered something..
lets say you are dealing with the number .9(repeating) ..
set N=.9(repeating)
if N=.9(repeating) then 10N=9.9(repeating)
10N-N=9.9(repeating)-.9(repeating)=9=9N
take 9N=9 and separate the N
9N/9=1
N=1
so... N=1 but N also = .9(repeating)

now i know that .9 repeating approaches 1 as it approaches the infinity position, but it never reaches 1...
Your problem occurs when, to me, you seem to arbitrarily say 9=9N.

I'm not sure where you're coming up with that.


As far as your other observation:
I think that the basic equality is flawed. I do not think that .1111--- is equivalent to 1/9, although on the surface it would appear to be the case.
