Summary

[edit]
Description
Português: Professor: Fabio Henrique Teixeira de Souza

Aritmética - Aula 44 - Cuidado! Cortes nem sempre valem em congruências. Classe inversa módulo n.

Nesta aula chama-se a atenção para o fato de que, em geral, não podemos cancelar um fator comum dos dois lados da congruência. Introduz-se a noção de inversos modulares. Construímos a tabela de multiplicação mod 8.

Observamos que alguns números têm inverso módulo 8 e outros não.
