A construÃÃo dos nÃmeros naturais: um foco nas quatro operaÃÃes fundamentais / The construction of the natural numbers: a focus on four fundamental operations

Pedro SÃrgio Sales de Sousa 28 November 2014 (has links)
O presente trabalho tem como objetivo apresentar a construÃÃo dos nÃmeros naturais e a definiÃÃo axiomÃtica no que diz respeito Ãs quatro operaÃÃes fundamentais para alunos e professores do ensino fundamental. Para isso foi apresentado uma sequÃncia abordando inicialmente as consideraÃÃes sobre o estudo da MatemÃtica, o conceito de MatemÃtica, o saber matemÃtico e um breve histÃrico matemÃtico para se perceber como teorias e prÃticas matemÃticas foram criadas, desenvolvidas e utilizadas num contexto especÃfico de cada Ãpoca. No segundo momento foi descrita a construÃÃo dos nÃmeros naturais atravÃs dos axiomas de Peano, prosseguindo com a definiÃÃo rigorosa de cada operaÃÃo e finalizando com a relaÃÃo de ordem no conjunto dos nÃmeros naturais. / This paper aims to present the construction of the natural numbers and the axiomatic definition with respect to the four fundamental operations for students and teachers of elementary school.To this was presented a sequence initially addressing on the study of mathematics, the concept of mathematics, mathematical knowledge and a mathematical brief history to see how mathematical theories and practices are designed, developed and used in a specific context of each era. The second moment was described the construction of natural numbers through the Peano axioms, continuing with the rigorous definition of each operation and ending with the order relation in the set of natural numbers.
