Number theory is the field of mathematics associated with studying the properties and identities of integers.
Contents
Overview
Number theory is a broad topic, and may cover many diverse subtopics, such as:
Some branches of number theory may only deal with a certain subset of the real numbers, such as integers, positive numbers, natural numbers, rational numbers, etc. Some algebraic topics such as Diophantine equations as well as some theorems concerning integer manipulation (like the Chicken McNugget Theorem ) are sometimes considered number theory.
