Download Free Textbooks

Introducing the first multimedia textbook of its kind.

Our free textbooks are PDF versions of common textbooks with embedded teaching videos, providing a deeper, richer learning experience for mathematics students.

Below you will find our textbook offerings and availability.

We produce undergraduate and test-prep textbooks, as pdf's. The pdf format allows us to hyperlink all of the cross-references in the books, to put in pop-up margin comments, and to embed videos at the beginning of each section - videos which teach students the content of the section. Consequently, our free textbooks are also electronic versions of courses.

The pdf format also means that our texts are ultimately portable; the student can have the textbooks on a laptop, an iPhone, a Kindle, or any other device that can display pdf's. In addition, the student can print any portions of a textbook that he/she desires.

Even if our textbooks are printed, and so all of the extra pdf features are missing, we still believe that our textbooks are superior to any others that currently exist. Our texts are written by award-winning teachers, and are written to emphasize ideas and examples. Technical details - the rigorous mathematics - is important in our textbooks, but we place these details at the end of each chapter, where they do not interrupt the exposition.

Our test-prep books are aimed at helping students prepare for the SAT's, GRE's, and other tests the old-fashioned way: by learning the material, not by learning test-taking tricks.
