.99=1
 
well here's my question, does .9999999 with that bar over it = 1? Best answer gets 500 points. (I say yes, check it out, .33 with the bar + .66 with the bar = two third + one third = 1) what do you think?

lim(m --> ∞) sum(n = 1)^m (9)/(10^n) = 1
0.9999... = 1

Thus x = 0.9999...
10x = 9.9999...
10x - x = 9.9999... - 0.9999...
9x = 9
x = 1.

Yeah, I didnt come up with that, I found it on page 3 of the Critical Thinking forum. It is undisputed that .999999 does equal 1 in this forum.
