x = 0.99999...

Multiply x by 10.

10x = 9.99999...

Subtract x from 10x and solve for x.

10x = 9.99999...

-x = -0.99999...

-----------------

9x = 9

x = 9/9

x = 1

Didn't we assign x as 0.99999...? Yes, we did. Then how did the

answer magically change to 1? It's not magic. It's just that

0.99999... was equal to 1 all along.

k? theres that one AND this one...

go to Calculator on your computer (or a normal calculator its up to you)

type in

1/3 (use fractions to decimles o get .33333333...)

then multiply that by 3

and you will get 1.... i thought .33333333333... * 3 = .99999999999...

why? i think that math is screwed up.... cos .9999999999 clearly does not = 1...
