    Is .99999999 with infinite 9s equal to 1?

    Can someone get this straight?

    In math, no, in practical computing terms, yes.

    But I thought if you had an infinite series it would equal to 1

    And since 1/9 is .111111
    .1111111x9=.9999999
    9/9=1?

    x = 0.999...
    10x = 9.999...
    10x-x = 9.999... - 0.999...
    9x = 9
    x = 1

    Nope. You start out already establishing x=.999... The next step is a pointless example that doesn't change anything. The third is right, but the forth is where you messed up. I don't know how you got to that, but that line shouldn't even exist.

    Simply worked out, 10x-x = 9. There is no 9x=9 or anything like that.
