Someone brought this up on another forum I go to.

The limit of 1/x as x approaches 0 equals infinity. But 1/0 is undefined, right? Can 1/0 be considered infinity?

What about the fact that mathematic operations should be reversible? If I have 1/2 and multiply it by two, I now have 1. If I have 1/0 and multiply it by 0... what do I have? And what did I just multiply by zero?

Do you usually learn more about this kind of thing in upper-level math classes? (I'm still trying to figure out what they fit into 4 levels of calculus)
