    Tables for a field

    How would you write the addition and multiplication table for a field with 9 elements?

    Well, it is finite and of power of prime order, 9=3^2 thus only one such fields exists up to isomorphism.

    That isomorphism is with \mathbb{Z}_{9}, the integers additive and multication modulo 9.
