What is math about?

The mathematical world.  Some philosophers — the Platonists — think math is about a mysterious other realm of eternal and unchanging entities. Others — the nominalists — think math is simply the manipulation of symbols according to rules we have made up. According to James Franklin, they’re wrong. His theory is Aristotelian realism: look around, and you can see math.
