Re: 0.9 repeating = 1?

I'm no math major (though I did make the mistake of taking a proof based Linear Algebra class once, never doing that again! ), but I don't really see the proof. Wouldn't accepting that 0.000... is equal to zero hinge on accepting that 0.999... is equal to one? What am I missing?
