Quick intro to number theory - 0 - Trailer

This playlist is a quick introduction to the basic concepts of modern number theory, with the goal of introducing the viewer to the tools that are needed to understand how modern cryptographic methods based in number theory work. We discuss divisibility, primes, the Fundamental Theorem of Arithmetic, the greatest common divisor, Euclid's algorithm, congruences, congruence classes, multiplicative inverses, Fermat's little theorem, finite fields, primitive roots, and the discrete log problem.
