0.99999999................... = 1


Wanna see the proof? Check it out.... Let's assume,
Let, x = 0.99999999999999.......................
=> 10x = 9.99999999999999.......................
=> 10x = 9 + 0.99999999999999...................
=> 10x = 9 + x
=>  9x = 9
=>   x = 1
So, 0.99999999999999............................ = 1
Is anything going wrong here?

    Here u hv used "EQUAL TO" sign. But actually it is "ALMOST EQUAL TO".
    In your 4th line of proof you hv assumed "0.999..." almost equal to x.

    2. I actually disagree :) I think the proof is legal and yes 0.9999.....(to infinity) does `equals` 1

    3. Naah, it is still almost equal, not exactly equal.
