General - 0.999....=1 - View Post

Because what is more fun than discussing math, right?

Also 0.999... is here used to denote a zero, followed by infinite 9s. Also reffered to as 0.9 reccurring, and many other things.

If                  x=0.999...

10x=9.999...

10x=9+0.999...

10x=9+x

 10x-x=9

 9x=9

 9x/9=9/9

  x=1

 

Alternatively:

1/9=0.111...

0.111...*9=0.999...

0.111...*9=1/9*9=9/9=1

 

What to people think about this?
