Discrete Algorithmic Mathematics

The product was brand new just like it said and shipping was very quick and arrived BEFORE projected date.

I found this book to be truly extraordinary. Unlike the overwhelming majority of math texts, the authors describe the material in a manner reminiscent of an informal college lecture by gifted professors. They cover a lot of ground, but explain what's going on and why. I found it particularly striking that the authors sometimes present mistaken approaches to problems, follow them through to show what has gone wrong, and then show how to avoid the mistakes. This is particularly valuable when using the book for self-study. The exercises are carefully chosen and serve to expand on each section's material.
