"I thought Math proved the existence of infinity?"
You did? Math deals with the concept of infinity, but does not prove the existence of infinity. You see, infinity + 1 is larger than infinity.
Math generally speaks of "approaching infinity". Infinity is a concept, not an actual number.
Yes, I know that infinity isn't an actual number. The number line supposedly does not end. The number line cannot end because there are unlimited numbers. I could sit at my computer and type 9 in my computer forever until I died, or the computer just couldn't handle it anymore (battery died, age of computer, processor, etc). I wouldn't ever do it, of course.

It's worse than that - in set theory there's the "axiom of infinity"
Also in set theory are the concepts of infinite "cardinal" and "ordinal" numbers. For ordinals, addition and multiplication are not commutative reference
But cardinal arithmetic is commutative reference
