Overview

This course on Number Theory aims to teach students the principles and concepts related to divisibility, linear Diophantine equations, congruences, and quadratic reciprocity. The course covers topics such as the Euclidean Algorithm, Fermat's Little Theorem, the Chinese Remainder Theorem, and the Mobius Inversion Formula. Students will also learn about primitive roots modulo p, the Legendre Symbol, and applications of quadratic reciprocity. The teaching method includes video lectures originally created for a specific semester. This course is intended for individuals interested in advanced mathematics and number theory.
