Euclid's theorem about the in ̄nitude of the prime numbers is a consequence of that theorem. In elementary number theory, this fact goes by the monicker \Fermat's Little Theorem" when n is prime and \Euler's Theorem" in general, and we reprove it from basic principles in this section. 1 Mathematical Induction 1. Number theory is primarily concerned with the properties of integers, with real numbers playing at best an ancillary role.
