Another comic discussion!

I want to talk about infinity.

See, how I see it is that if Infinity divided by a finite number is infinite, any finite number divided by infinity is a number infinitesimally larger than, but never equal to, zero you must also realise that Infinity divided by infinity is one or in fact any other positive number. Take into account also that Infinity multiplied by zero is zero and that Infinity divided by a positive finite number is infinity, Infinity divided by a negative finite number is minus infinity and Infinity plus infinity is infinity but Infinity minus infinity, due to the nature of infinity, can be zero, infinity, or minus infinity. So looking at all respects infinity appears to be a number; as it shares some of the same properties. Unfortunately, when you start using it as a number, you experience a few problems. So you might be thinking, so why isn't Infinity a number? Well, if it is, then it is each and every imaginable and unimaginable number, while being none of them. If you can define a number, it isn't infinity.
Therefore, infinity is not a number, right?

That's not very scientificall approach to infinity, isn't it? Anyone read Lem's story about hotel with infinite number of rooms?

[YarpsDat]

The only problem with infinity begins when you want to calculate infinity-infinity, infinity/infinity or infinity*0.
Because then the result depends on the type of infinites used.
Other than that infinity is simple.
