Why do you fucking retards return every time this thread occurs? I can only hope that each time I post this, one person is convinced, that way, assuming there is only a finite number of idiots here, eventually you will all learn.
Let:
x = 0.999~
Multiply both sides by 10.
10x = 9.999~
Subtract 0.999~ (which is equal to x) from both sides.
9x = 9
Divide both sides by 9.
x = 1
We began by stating that x = 0.999~, therefore.
0.999~ = 1
A proof that requires nothing more than middle-school algebra. Satisfied?
