Intermediate Number Theory Online Math Course

Intermediate Number Theory

Number theory using algebraic techniques, multiplicative functions, Diophantine equations, modular arithmetic, Fermat's/Euler's Theorem, primitive roots, and quadratic residues. Much of the first half of the class emphasizes using the basic tools of the Introduction class in clever ways to solve difficult problems. In the second half, more theory will be developed, leading students to the beginning Olympiad level.

After taking this class, I am solving AIME-IMO Number Theory Problems. This class really builds the foundations necessary for Olympiad Number Theory problems. It is also very problem-solving oriented which is great. I've learned so much from this class; Keep up the great work AoPS!
