Discrete Math Resources Page
(The Discrete Math Hub)
(If you're looking for Prof. Bard's textbook in progress, Discrete Structures in
Mathematics---A Problem Solving Approach, then
What is this website?
The goal is to make a repository for all the free resources about Discrete
Mathematics throughout the internet. When this site opened on September 7th, 2017,
there were only a few resources here. The idea is that faculty teaching this course (or
students) will notify me whenever they come across anything new, and I shall link to it.
(You can contact me via the e-mail address at the bottom of this page.) I've added a few
things that I've found on my own.
Over time, it has become be a large and useful compilation.
Without such a central repository, faculty are all working in isolation. For example,
when I create a resource, it helps only those students on my particular campus,
The University of
Wisconsin---Stout (Wisconsin's Polytechnic University), in Menomonie, Wisconsin. With
a website like this, faculty all over the world can share their work, and avoid any
duplication of effort.
Free Textbooks for Discrete Mathematics
These are listed in reverse alphabetical order by the first author's last name.
(It is in reverse alphabetical order to avoid forcing me to list my own books
- Oscar Levin, Discrete Mathematics---An Open Introduction
is a textbook that has been endorsed by the American
Institute of Mathematics Open Textbook Initiative. I enjoy it thoroughly, and it is
great in general, but superb for future high-school teachers in particular.
The electronic version is free and
you can find the print softcover
version on amazon.com for a very low price.
(It was only $12 (USD) on September 7th, 2017.)
- Alan Doerr and Kenneth Levasseur, Applied Discrete Structures is another
textbook that has been endorsed by the American
Institute of Mathematics Open Textbook Initiative. It is free in
but I have not read it yet, so I cannot say more.
- Edward A. Bender and S. Gill Williamson, Discrete Mathematics: First &
Second Course is yet another
textbook that has been endorsed by the American
Institute of Mathematics Open Textbook Initiative. It is also free in
but I have not read it either, so I cannot say more.
- Gregory V. Bard, Discrete Structures in Mathematics---A Problem Solving Approach
is a work in progress. The goal is to create a free textbook with lots of examples related
to real-world applications in computer engineering, computer science, and game design.
There are also applications to biology and other sciences. This electronic
hosted on this website.
The goal is to someday earn the American Institute of Mathematics
Open Textbook Initiative endorsement as well.
- The following three books are endorsed by the American
Institute of Mathematics Open Textbook Initiative, and are listed under the
category of Introduction to Proofs. That is often a painful subject for students,
so it is nice to give them lots of resources.
- Ted Sundstrom, Mathematical Reasoning: Writing and Proof,
- Richard Hammack, Book of Proof,
- Joseph E. Fields, A Gentle Introduction to the Art of Mathematics,
- While it is not free,
Kenneth Rosen's huge encyclopedia Discrete Mathematics and Its Applications
is a cornerstone of this subject. It is certainly not cheap (e.g. a new hardcover copy
cost $223.39 (USD) on amazon.com on September 7th, 2017.)
However, it is a great reference, especially for advanced topics. Prof Rosen spent most of
his career at Bell Labs, so there are
many telecommunications-related applications.
Other Relevant Books
These are also listed in reverse alphabetical order by the first author's last name.
(Again, it is reverse alphabetical order to avoid forcing me to list my own books
- William Stien, Elementary Number Theory: Primes, Congruences, and Secrets: A
Computational Approach was published by Springer in 2010, as part of their series
"Undergraduate Texts in Mathematics" (UTM). Number theory and cryptography are usually
the last two chapters of a course in Discrete Mathematics. Therefore, students might like
to read this book over break after completing their Discrete Mathematics course. By the
way, William Stien is the founder and chief architect of the free computer algebra system
"Sage." This book is also free in electronic form,
and the printed hard cover is very inexpensive on
amazon.com. (It was only $39.96 (USD) on September 7th,
- Gregory Bard, Sage for Undergraduates is a book about the free computer
algebra system Sage, sometimes called SageMath. Published by
The American Mathematical Society
in 2015, this book has been written for the
Calculus ii (integral calculus) or Calculus iii (multivariate calculus)
student, but includes chapters on much more advanced undergraduate courses in mathematics.
(Also, Ch 5 teaches the computer language Python.) You can be very functional with
Sage just by reading the first chapter. This book also has been endorsed by the
American Institute of Mathematics Open Textbook
Initiative. It is
electronic form, and the softcover printed
version is very inexpensive on amazon.com.
(It was only $29 (USD) on September 7th, 2017.)

of all mathematics textbooks that have earned the endorsement of the Open Textbook
Initiative of the
American Institute of Mathematics. For more information

- Prof Lawrence Riddle of Agnes Scott College has made an excellent page about how you can get
a famous fractal (Sierpinski's Triangle) by starting with Pascal's triangle, and then
coloring in the even entries in one color, but the odd entries in a different color.
- For those who don't know what fractals are, Prof Riddle also has a page that talks
about the highly related Sierpinski's gasket and the 3D version of that, Menger's sponge.
The reason Menger's sponge is interesting is because it has finite volume but infinite
surface area. Even if you can't follow the formulas, the pictures are great.
- The most famous Monte-Carlo Simulation of all time is probably that of throwing
darts at the unit square---the set of points (x,y) where both x and y are between
-1 and 1. One counts how many darts are inside the unit circle. For an enormous number
of darts, this will be roughly pi/4. I made a demo of this using SageMathCell.
- I hope to add many more to this list, when time permits. If you find something
good, please send me an email. (My email address is at the very bottom of this page.)
Official Standards and Syllabi
- The IEEE (Institute of Electrical and Electronic
Engineers) and the ACM (Association of Computing
Machinery) made an official document in 2013 that hopes to define what anyone
with a Bachelor's Degree in Computer Science should definitely know.
This updates similar documents from 2008, 2001, and the 20th century.
- There are six pages talking about discrete math, which they call 'the discrete
structures knowledge area.'
Click here for that.
- In addition, in the appendices, they offer three syllabi of exemplary courses:
- Portland Community College does it two semesters. It is four hours per week
for an entire academic year! (8 credits, 80 total hours)
- Union County College does it one semester. (3 credits, 42 total hours)
- Stanford University does it in two quarters (trimesters) of 10 weeks. (? credits, 38 total hours)
'CS103: Mathematical Foundations of Computer Science,'
and 'CS109: Probability Theory for Computer Scientists.'
Combined File Note:
these two courses are available for free, on the web! (This is includes the schedule, the problem sets,
exams, etc...) The link can be found below.
- To this, I'd like to add the UW Stout course document. We were not at all included
in the official report.
Official Description. (3 credits, 42 total hours)
- For the entire 518-page document,
- Separate from that, the CRAFTY (Curriculum Renewal Across the First Two
Years), a subcommittee of the Mathematical Association of America, ran the
Curriculum Foundations Project: Voices of the Partner Disciplines, from
November 1999 to November 2001.
The idea was to talk to experts from other disciplines, to learn what should be taught
to undergraduates in various majors (e.g. Chemistry, Business Management, Physics,
Biology, and many separate branches of Engineering).
- Chapter 5 deals with Computer Science, and much of it is a description of a
discrete mathematics course. It is 13 pages, and while it was completed in 1999, it
seems to still be very relevant.
- For the entire report, including all disciplines,
click here. (It's actually rather fun to read about what mathematics gets actually
used in subjects like Chemical Engineering.)
Links to other resources
- As noted earlier, Standford University has generously put the two courses that it uses
for discrete mathematics, on the web for free!
- Wikipedia---the free online encyclopedia---has a large article on
Mathematics including several of its applications. While I frequently read
and donate my time and some money to that website, and love it, I must confess that the
math articles are often extremely hard to read.
- MathWorld is another free encyclopedia.
However, unlike Wikipedia, the articles are thoroughly checked and signed, and are often
easy to understand. Discrete Mathematics is one of their 11 high-level subdivisions.
- The SageMathCell server is an extremely
quick way to do computations in Sage when you're on the go. (Sage is a free computer
algebra system, the open-source competitor to Maple, Mathematica, MAGMA, and
- The following article is by a professor who is a veteran discrete mathematics instructor,
and author of a successful textbook for discrete mathematics. Her research area includes techniques
for teaching students about proof writing. I find the insights to be extremely true, relevant, useful,
and deep. I highly recommend this article to any instructor of any undergraduate mathematics course
that involves proof writing.
