There are five of them, also known as Peano's axioms:

1. 0 is a number.
2. If n is a number then n's successor is a number.
3. 0 is not the successor of a number.
4. If two numbers have successors that are equal then the numbers themselves are equal.
5. If S is a set that contains 0 and also the successor of every number that is in S then every number is in S.
