Here's something I found on a different forum lol:
c = 0.999...
Multiply by 10
10c = 9.999...
Subtract c from both sides
10c - c = 9.999... - c
Substitute 0.999... for c on the right side of the equation
10c - c = 9.999... - 0.999...
Simplify
9c = 9.000...
Since we know that repeating zeros do not affect a numbers value
9c = 9
Divide both sides by 9
c = 1
Since
c = 1 and c = 0.999...
1 = 0.999...
RAWR!

this is actually wrong. im sorry to be the bearer of bad news, but i showed this to my mom, who's a big math person, and figured out that it was wrong.
10c - c = 9.999... - 0.999...
Simplify
9c = 9.000... 10c - c doesnt equal 9c there ya go. it's almost right, but just that one thing throws it off....

sorry. that was wrong... oops. so i dont know now... nobody could figure it out... now im confuzzled. cuz 10c-c = 10c-1c so you do the like term thingy, so its 9c.

so far, the only "flaw" i can find is that theres a difference when you plug in c for .999...., because 9*.999....=8.991 (i only used 3 9's) 9c and 9*.999... are diffrnt. other than that, its right, as far as i can see. well, lets put it in better wording- i cant find where its wrong yet.....
