Introduction to number theory
This text gives an introduction to the many facets of number theory, including tastes of its algebraic, analytic, metric, Diophantine and geometric incarnations. We assume the reader has taken a first course in algebra and has familiarity with groups as well as modular arithmetic.

Introduction to Number Theory - Math is Fun
We only have integers, which are whole numbers, their negatives, and zero: This is Number theory, a branch of mathematics that explores the properties and relationships of integers. The cool part is that anyone can join in; it is mostly basic operations like multiplication and addition!

Number theory - Wikipedia
Number theory is one of the oldest branches of mathematics alongside geometry. One quirk of number theory is that it deals with statements that are simple to understand but are very difficult to solve.

Number Theory - Mathematical Association of America
Number theory is an attractive way to combine deep mathematics with fa-miliar concrete objects and is thus an important course for all mathemat-ics students: for \straight" mathematics majors, for pre-service high school teachers, and for students who are preparing to go to graduate school.
