Book Description

A Friendly Introduction to Number , Fourth Edition is designed to introduce readers to the overall themes and methodology of mathematics through the detailed study of one particular facetâ€”. Starting with nothing more than basic high school algebra, readers are gradually led to the point of actively performing research while getting a glimpse of current frontiers. The is appropriate for the undergraduate audience and includes many numerical examples, which are analyzed for and used to make conjectures. Emphasis is on the methods used for proving theorems rather than on specific results.
