Hey number lovers! In this video we are going to explain the principles of modular arithmetic. This branch within the Number Theory focuses on the relationship that integers have with the remainders obtained when they are divided by another number, introducing the concept of modulus. As a curious fact, I have improved the quality of the microphone with which I record, now I can be heard much better :) 0:00 Introduction 0:22 Concept of congruence 2:35 Properties of congruences 7:18 Exercise 1 9:48 Exercise 2 14:53 Final Any questions in the comments :) Don't forget to subscribe for more content! #arithmetic #modules #modulararithmetic #numbertheory #algebra #principles #mathematics #integers #systemsofequations
