0.999 = 1

don't believe me? check out this proof:

let x = 0.999

10x = 9.999

10x-x = 9.999 - 0.999

9x = 9

x=1

therefore, 0.999 = 1.
fancy!

x=0.9990000 (didn't say 9's went to infinity)

10x = 9.990
10x-x = 9.990-x
9x = 9.990-x
8.991 = 8.991

yeah yeah yeah, i didn't know how to put the infinity bar on top of the last 9.

but thanks to your refutation, i reviewed the concept and found it to be flawed. in line 3 (of mine) i subtract the variable, "x" from the left, and i subtract the value of "x", 0.999, on the right. you can't do that. you have to be consistent. if i used both x's or 0.999's, the equation equals out. damn i thought that was smooth, but there something to be said for learning. danke JHo.
