Intermediate Number TheoryThese are more complex number theory theorems that may turn up on the USAMO or Pre-Olympiad tests. This will also cover diverging and converging series, and other such calculus-related topics. Useful facts and FormulasAll quadratic resiues are 0 or 1 |
and 0,1, or 4

Fermat-Euler Identitity-If 
, then 
, where 
is the number of relitvely prime numbers lower than
