My Books

I have published several books in the following subjects (I’ve been writing for decades, though didn’t start publishing my material until 2008):

  • math books (including arithmetic, prealgebra, algebra, geometry, trig, logarithms, and calculus)
  • science books (including physics, astronomy, and chemistry)
  • puzzles (math puzzles and word scrambles)
  • self-publishing on Amazon (detailed how-to guides, toward the bottom of the page)
  • hobbies (chess and golf log books)

Below I describe and list my books. They are arranged by topic in the same order as the list above.

Alternatively, you can visit my author page at Amazon (see the link below). The problem with my author page is that Amazon defaults to my Kindle ebooks. Most of my older books are only available in paperback, and even with my newer books, most customers buy the paperback edition because it is convenient to write solutions on the paper, highlight, take notes, etc. If you visit my author page at Amazon, where it says “Books by Chris McMullen,” click the Paperback rectangle to see all of my books instead of just those that are ebooks.

My most popular math book is Algebra Essentials Practice Workbook with Answers, which has a ton of practice problems. The key to developing algebra fluency is ample practice. Note that the answers are in standard form, so if you don’t rationalize the denominator or factor out perfect squares, you might get a different answer than the answer key has. (To make matters worse, some of the popular online algebra calculators don’t express their answers in standard form. As a result, a few customers have mistakenly believed that an answer in the book was incorrect, until they took the time to contact me by email, allowing me to politely show them that they hadn’t rationalized their denominator, factored out a perfect square, or reduced a fraction.) Here is a tip: If you’re confident with your answer, enter your answer and the book’s answer on your calculator and see if they are the same in decimal form.

My newest algebra book, Master Essential Algebra Skills Practice Workbook with Answers, is 388 pages (twice as long as my first algebra book), with more variety in the types of problems, and much more instruction. While it has a greater variety of problems, it doesn’t have nearly as many problems for any specific topic. The two algebra books go nicely together. My newer algebra book is more focused on the ideas and techniques, whereas my original algebra book is focused more on a ton of practice for the most important techniques.

Here is a list of my math workbooks from prealgebra onward (for arithmetic workbooks, keep reading once this list ends).

  • Essential Prealgebra Skills Practice Workbook (new release)
  • Algebra Essentials Practice Workbook with Answers (to my surprise, it has spent several weeks as #1 bestseller in Algebra on Amazon over the years)
  • Master Essential Algebra Skills Practice Workbook with Answers (new release, my longest and most comprehensive algebra book)
  • 50 Challenging Algebra Problems Fully Solved (the level of difficulty varies, they are intended to be doable by good students who are fluent)
  • Algebra Word Problems Practice Workbook with Full Solutions (also available as an audio book with the amazing voice of Gracia Gillund who did an incredible job reading the book, great if you’re looking for word problems)
  • Systems of Equations: Substitution, Simultaneous, Cramer’s Rule (an entire book devoted to systems with two or three unknowns)
  • Basic Linear Graphing Skills Practice Workbook (thorough coverage of graphing ordered pairs, finding slopes and intercepts, equations for a straight line, etc.)
  • Geometry Proofs Essential Practice Problems Workbook with Full Solutions (all about the art of proofs)
  • Trigonometry Essentials Practice Workbook with Answers (my most popular trig book, it offers ample practice; I also have a flashcard ebook on Kindle for memorizing the trig functions for common angles in all four Quadrants)
  • Learn or Review Trigonometry Essential Skills (offers more instruction, introduction of concepts, variety of problems)
  • Logarithms and Exponentials (learn what a logarithm means, practice a variety of calculations, also covers exponentials, graphs, hyperbolic functions, and complex numbers)
  • Essential Calculus Skills Practice Workbook with Full Solutions (a fan favorite)
  • 50 Challenging Calculus Problems Fully Solved (includes some classic, well-known problems; the level of difficulty varies, they are intended to be doable by good students who are fluent)
  • The Four-Color Theorem and Basic Graph Theory (a really accessible introduction to the basic ideas of graph theory, just about anyone can understand it without any background, even middle schoolers who are good at math; this book provides comprehensive coverage in terms of ideas relating to the four-color theorem in a very accessible way, and important ideas of graph theory and presented in a way that’s easy to understand, not like the typical language of books or articles on graph theory; this book is also rich in new ideas and approaches and new ways of looking at things — I probably could have published a few papers by pursuing a few of these ideas more fully, but wanted to keep this book accessible; this is perhaps one of the most “important” works I’ve written in terms of the quality and uniqueness of ideas presented, but it’s also a fun book)
  • The Visual Guide to Extra Dimensions (two-volume set; this is the first book I ever published, based on my lifelong curiosity about a possible fourth dimension of space; it provides an accessible introduction to the fourth dimension, some knowledge of basic geometry may be helpful; many cool topics are covered, and many unique diagrams are presented)
  • Amazon’s Downloadable Educational Resources for Parents or Teachers (I have a handful of books in this new Amazon category, so far with fractions, decimals, algebra, and chemical equations; don’t search in Books; visit Amazon and change the category to Downloadable Educational Resources; these digital books are PDF’s and you may print out the pages; if these become more popular in the future, I will add to my collection)

For arithmetic, fractions, long division, percents, and grade level workbooks, see this list:

  • Grade 6 Math Workbook with Answers (I wrote this when my daughter asked me if she could test out of 6th grade math; she used it over the summer and tested out of 6th grade with 93%, and earned an A in GT Math 7th/8th grade combined the following year)
  • Grade 5 Math Workbook with Answers (and other grade levels to be released in the future)
  • Master Long Division (starts out with facts, the divisors and dividends grow as the book progresses, finishing with remainders; I actually have two similar books, the newer one with Remainders in the title includes a step-by-step example to begin each chapter; the older one is a little less expensive and just has a ton of practice problems)
  • Fractions, Decimals, and Percents Math Workbook (all about converting between fractions, decimals, and percents)
  • Fractions Essentials Workbook with Answers (comprehensive coverage, includes instruction and examples)
  • Practice Adding, Subtracting, Multiplying, and Dividing Fractions Workbook (provides a ton of practice problems to build fluency; there is also a similar book with the word Mixed in the title which just has mixed fractions)
  • 7000 Multiplication Problems Practice Workbook (includes answers)
  • 10,000 Addition Problems Practice Workbook (includes answers)
  • 10,000 Subtraction Problems Practice Workbook (includes answers)
  • I also have some workbooks dedicated to learning the facts (my newer multiplication book includes answers, and I also have one with two-digit numbers 10 thru 20 for those who want to learn beyond 10)
  • Pyramid and Radial math workbooks present arithmetic problems visually and in color


Covers Science

I’ve published physics books that I’ve used in my own classroom, and popular astronomy and chemistry books. (I have over 20 years of experience teaching physics at universities in California, Pennsylvania, Oklahoma, and Louisiana. I wrote the math books with the goal of helping students become more fluent in math. Hence the name of my math series, Improve Your Math Fluency.)

  • Essential Calculus-Based Study Guide Workbook (Volumes 1-3, provides a concise introduction to the essential ideas for each topic, presents problem-solving strategies, and includes many helpful examples with step-by-step solutions and explanations; I bought author copies and passed them out free of charge to my students when I was teaching, and I’ve received great feedback about this series)
  • Essential Trig-Based Study Guide Workbook (Volumes 1-3, just like the previous set except it doesn’t have any calculus; again, I passed out author copies to my students free of charge when I was teaching)
  • 100 Instructive Calculus-Based Physics Examples (Volumes 1-3, this is basically the solutions manual to the Study Guide Workbook described above, but is also great if you just want to read through 100 examples)
  • 100 Instructive Trig-Based Physic Examples (Volumes 1-3, this is basically the solutions manual to the Study Guide Workbook described above)
  • Essential Modern Physics Study Guide Workbook (includes relativity, quantum physics, and an introduction to Schrodinger’s equation)
  • An Advanced Introduction to Calculus-Based Physics (Mechanics only; I wrote this when I was teaching advanced students, and again I passed out free copies to the students)
  • A Guide to Thermal Physics (starts out at the first-year level and finishes at the level of Callen; I used this when I had a small class of very advanced students)
  • Creative Physics Problems (Volumes 1-2, available with or without calculus, features my “famous” monkey problems)
  • An Introduction to Basic Astronomy Concepts (I was featured in a local newspaper article regarding this book, and over the years it has spent some weeks as the #1 Bestseller on Amazon in astronomy subcategories; it’s very accessible, even kids or adults can read it)
  • Basic Astronomy Concepts Everyone Should Know (this has the format of an illustrated children’s book and isn’t as comprehensive as my more popular astronomy book)
  • Balancing Chemical Equations Worksheets (chemistry students and teachers love this comprehensive list of reactions to balance, but even math puzzle lovers enjoy these)
  • Understand Basic Chemistry Concepts (focused on the main ideas behind chemistry, very accessible)


Covers Scrambles

  • 300+ Mathematical Pattern Puzzles (my most popular puzzle book, it introduces puzzles by topic; find full explanations in the back)
  • Pyramid Math Puzzle Challenge (more challenging puzzles due to the layout of the puzzles and the fact that they aren’t organized by topic and there isn’t any text telling you about different kinds of patterns beforehand; if you find this too challenging, try starting with my other puzzle book first)
  • VErBAl ReAcTiONS (I thought these were pretty cool puzzles since they are anagrams that use symbols from the periodic table to make words, like GeNiUS, instead of the usual anagrams with letters; you don’t need to know any science, they are just cool anagrams for people who appreciate math or science; many thanks to my coauthor for doing most of the hard work)
  • Word Scrambles (many thanks to my coauthor, Carolyn Kivett, for doing most of the hard work, we have word scrambles for kids, spooky word scrambles, Christmas word scrambles, word scrambles for golf, word scrambles for football, military word scrambles, positive word scrambles, and even Word Scrambles that Make You Think; a great feature of these books is that there is a separate section for hints and answers, where the hint just gives you the first letter of the word in case you are stuck; another great feature is that the problems come in groups, where the first letter of each group forms an anagram for the group answer, which helps you figure out the ones that you don’t see right away)


Covers SP

If you wish to publish your own book on Amazon, I have some very detailed guides that can help you with your quest (from formatting to publishing to marketing):

  • A Detailed Guide to Self-Publishing with Amazon (Volumes 1-2; these books are so content-rich and helpful that I myself keep them handy)
  • Word to Kindle Formatting Magic (because formatting for Kindle isn’t as intuitive as it could be)
  • How to Self-Publish a Book on (a great place for new authors to start out)


Covers Hobbies


I enjoy chess and golf. When I first started publishing books, I made these to help master the art of publishing before publishing my math and science books. I wrote these books for myself, but others have found them helpful, too.

  • The Chess Match Log Book (great for recording games)
  • Make a Personalized Book of 500 Chess Positions (great for drawing chess diagrams)
  • The Golf Stats Log Book (a little large for a stats book, but it has more detailed stats than just the most basic ones for golfers who appreciate this)
