The following resources prove instrumental in understanding number bases. These serve as the backbone for work that appears throughout this website. If you are really into number bases, these titles should appear in your library or bookmarked on your browser. One does not need to understand the entire resource to have a good command of what makes a number base work, however, if one is interested in mathematics, many of these resources are basic to the field of number theory.

A good place to start would be Dudley. It is plainspoken but authoritative, with exercises for each chapter. Dudley presents proofs and challenges the reader. Answers to odd-numbered problems appear in the back of the book. Section 13 deals with numbers in other bases, and 14 with duodecimal. The book is like a friendly professor in paper form.
