just to show that it's kind of silly. It isn't a proof but rather an

illustration. I think that a lot of background work is required to show

that 0.9999.... is exactly equal to one and given that background, Angela's

proof is sufficient. Your demonstration is just as silly as mine since

alpha being an infinitesemly [sp?] small value means that it is exactly

equivalent to zero right?

RK had cleverly pointed out that using different numerical bases can

demonstrate these things too. In base 3, 0.1 = 1/3 and 0.1 + 0.1 + 0.1 = 1.

Anyway, I'm afraid that the 'proof' I clipped from Slashdot was not

mathematically rigorous enough for this audience. (Wow! Tough crowd...take

my wife, please.... but I think it did serve it's original purpose of

satisfying RK.

x = (9 - 9*x) / 9 = [9*(1 - alpha)] / 9 = 1- alpha,

^^^^^^^^

sorry, it should be

x = (9 - 9 * alpha)/9
