4th Edition Information

This page details progress on the 4th edition of the book. The 3rd
edition remains available.

After many years of development, I am please to announce that the 4th
edition of Discrete Mathematics: an Open Introduction is now
available, here and on Runestone Academy.

The new edition brings many improvements and a new organization of
content. In particular, the book now starts with logic and proofs,
then practices those proofs with graph theory. The second half of the
book contains material on counting (with a new "application to
probability" section) and sequences. Over the last few years, I have
found that students have more success with this arrangement. There is
also a stronger emphasis on discrte structures, which should make the
book more useful for students in computer science, while still
focusing on understanding mathematical concepts essential for math
majors and future math teachers.

There is more interactivity as well. More interactive exercises
(which you can give students credit for if you create a course with
the book on Runestone Academy; it is completely free for you and your
students) and some interactive Sage and Python code to explore some
topics.

A PDF of the book will be made available soon. There will not be a
print edition available until next year, when CRC Press will release
it. The online version will remain available and free forever, and
the book is still released under a Creative Commons License (but note
the new NC-Non Commercial addition to the license).
