Infinity is not a number it is a concept. You can't technicaly do algebra with infinity.
One of my math teachers and I had a discussion aboot this. There are actually different types of infities, and I may have to take a class that is like mathematics of infinity. You can do some weird calculations with it apparently. But yes Eric, by the laws of limits .99~ is 1.
I also had a discussion with one of my engineering professors who said that it is impossible to ever get to exactly the right position with a hole or something of that sort. That you will always be at .99~ or .000001. I tried to reason that at some point you MIGHT hit exactly 0. But he's still pretty much right.

0.999... = 1 - 1/∞
since 1/∞ does not equal 0 (however close it may come),
0.999... does not equal 1.
QED.

if you cant prove that the proofs are wrong then they are correct, and if they are correct then .9~ = 1

I would like to take this moment to say that our little boy, Eric, is growing up. He has developed reasoning skills. Honey I'm so proud of you. Just letting you know that mama loves you.

you cant divide a number by infinity.
if you cant prove that the proofs are wrong then they are correct, and if they are correct then .9~ = 1
