...it's mathematically fallible. Consider:
(Infinity) + 1 = (Infinity)
(Infinity) * 2 = (Infinity)
or even
(Infinity) * (Infinity) = (Infinity)
If the universe is indeed expanding, it follows there MUST be some change in its size from state 1 to state 2. However, since
(Infinity) - (Infinity) = 0
it follows that an infinitely large universe would be a static one.

I think you misunderstood. When I wrote infinite, I didn't mean infinite in size, but that it exists infinitely without an event to start it or end it. You wrote that there has to be a starting point and my reply was basically something like "how do you know that"?
