How many possible bitcoin addresses are there?   Since I don't know the math that takes place, how are they calculated?  If it's by each client, how many possible per person?

It is pitch black. You are likely to be eaten by a grue.

The full answer:  2^160; they are randomly generated; they are all shared by everyone, but 2^160 is an enormous number and everyone can use as many as they like with no concerns about running out or accidentally generating a duplicate address.

There are about as many possible bitcoin addresses as there are atoms in the earth.
