this question really depends on your belief in the propose of math/calculation and the definition of infinity.

@sem2093
Why is dividing 1 by 3 the same as dividing 0.999... by 3?
1/3 = 0.333...
2/3 = 0.666...
3/3 = 0.999...

or

1/9 = 0.111...
2/9 = 0.222...
3/9 = 0.333...
4/9 = 0.444...
5/9 = 0.555...
6/9 = 0.666...
7/9 = 0.777...
8/9 = 0.888...
9/9 = 0.999...

If we allow 0.99999... to equal 1 then we'd also have to accept that 7.99999.... equals eight. Math is a tool of measurement and rounding up or down is a stray from preciseness in the answer.

Anyway. Yesterday I was infinite far. As in infinite close to eating a Cheese burger.. Eating one is 1.

0,9999... is far from equal 1...As in infinite far. And as in infinite close.

Can't use infinity in the way con has used it in their argument (algebraically), mathematically invalid. Pro's refutation of this argument is equally invalid because it uses infinity in the same algebraic manner (not that it matters because it's not a mathematically correct argument in the first place).

Pro's proof on the other hand is correct as it doesn't use infinity inappropriately (0.999... correctly identified as a rational number).

I am surprised that out of all of the things you could have chosen to attack in my argument, you chose to say that my 9's had to many points before them.
