The modular inverse via Gauss not Euclid
We demonstrate a lesser-known algorithm for taking the inverse of a residue modulo p, where p is prime. This algorithm doesn't depend on the extended Euclidean algorithm, so it can be learned independently. This is part of a larger series on modular arithmetic: https://www.youtube.com/pl

Modular Inverses, Generators, and Order: Linking Elementary Number Theory and Abstract Algebra
Solution to the unique number question posed at 5:01 We show two solution: one is more informal using intuition, and the other using congruences 1) Using Intuition We use a proof by contradiction: suppose that you can reach the same number twice WITHOUT first cycling back to 0. But since y

How does cryptography ACTUALLY work?
In this video I'll attempt to introduce you to some of the maths behind modern cryptography, which is in a sense how the world around us works now. Surprisingly, it has a lot to do with the simple ideas of division and remainders. We'll cover modular arithmetic basics, continued fractions

Why RSA encryption actually works (no prior knowledge required)
In this video, I am going to show you why RSA encryption works. I will prove the correctness of RSA from scratch, so no prior knowledge will be required. All results from number theory needed to understand why RSA works will be proven along the way. 00:00 1. Introduction, outline and disc
