Am I correct in assuming that you can make sense of [itex]\infty + \infty[/itex] and [itex]\infty + c[/itex] for any [itex]c\in \mathbb{R}[/itex] (both evaluate to [itex]\infty[/itex]), but that we can make no sense of [itex]\infty - \infty[/itex]?
Are there any other arithmetic operations one can perform with infinities that are undefined?
