O uso do princípio fundamental da contagem e estratégias para abordar e desenvolver a análise combinatória

Abstract

This work aims to facilitate the understanding of Combinatorics in High School and to be also a reference material for teachers who teach this subject. Here, we seek to illustrate how it is possible to construct all Combinatorics without being restricted to the use of formulas, taking the PFC - Fundamental Principle of Counting - as a base, and not using Arrangements and Combinations. These two issues will be worked out, but not as a reference. The versatility and applicability of Combinatorics are presented in a way to make it available for use by other teachers and students as well, through the resolution of different problems. In various situations, our aim is to establish important reasonings important and illustrate several problems in order to make students and teachers understand that it is extremely important to show all the process and to put oneself in the place of the one who is performing the task proposed in the statement
