0.999999.... = 1 see:

[math]
10r-r = 9. \overline{9} - 0.\overline{9} = 9 \Rightarrow r = 1

what does 10 * 0.99999... mean?

>> No.12372802

>>12372179
1 represents the entire infinite range, from 0.000... to 0.999...

it is a discrete, normal number, but it represents an infinite set. pretty based

10 * (r- r) = 10
10 - 10 = 0
r = 1

discrete, yet infinite. And yet math was supposed to be the epitome of logic. Sad!

Suppose, for a contradiction, that .9999... = 1. Multiply by 2 to get 1.8181818.... = 2. Since 1.8181818... < 1.9 < 2, there is a contradiction.

0.9999999...*2 does not equal 1.8181...
It equals 1.999999...

Your multiplication is wrong you add the 1 to the 8 in from of it not make a new space for it.
