Is infinity plus one equal to one plus infinity? What is infinity times
zero? Is infinity even a number? What are numbers anyway? Are there
different sizes of infinity? How does infinity come up in ordinary
mathematics? Do we need infinity to add real numbers?
I will survey these puzzles and give some rigorous answers.
