Book Description

0962781576 978-0962781575 January 1995 1
A fun little book which contains no exercises but rather simply explains the concepts, strategies, and vocabulary of algebra. What are polynomials and why do I care? What's a quadratic equation and how do I solve it? How do you multiply polynomials? What is the slope of a line? What are functions? The language is clear and often amusing. The authors assume the reader has no knowledge of algebra, and also assume he or she has forgotten how to multiply fractions and other preliminary processes. Not a stand-alone text, but a book to read on a Saturday afternoon before taking your first algebra class, it touches nearly all the concepts of a first year course. It has been used and praised by eighth grade students as well as college students. A wonderful refresher before taking a college entrance exam or graduate admissions test.

Editorial Reviews

Review

Algebra Unplugged is unlike any other mathematics text about algebra. Through the use of creative analogies, the authors explain the areas that are often stumbling blocks for students. -- Mathematics Teaching in the Middle School

An excellent and enjoyable book. Worth having several copies around to loan to students. -- The American Mathematical Monthly

It's a remarkable little book by Kenn Amdahl, a poet and former math-phobe and Jim Loats, a math professor. Be advised that Algebra Unplugged does not take the approach that your high school math teacher and textbook took. It certainly answers some basic questions differently. Amdahl and Loats cover pretty much all the topics of first-year algebra and a great deal of earlier math that many kids don't really have a grip on. And they do it all in just 258 pages of remarkably readable and often hilarious text.

Both of my daughters read the book. One, a true math-phobe probably managed to pass algebra in ninth grade as much because of this little book as because of her teacher. My other daughter profited as well, though she's a math lover. Bruce M. Smith, managing editor. -- The Phi Delta Kappan, Feb 1998

Sometimes, despite endless explanations by teachers and dozens of homework assignments, students don't always grasp algebra. Some ask for help, others turn to books, hoping that one will explain things in language they can understand. This may be the book they are looking for. Explanations are short, humorous, and non technical. The authors convinced this reviewer that there is value in sneaking up on a potentially intimidating subject in this way, although I was not so sure at the beginning. -- Appraisal-Science Books for Young Adults

The book contains no exercises. Instead, it simply explains the concepts, vocabulary and strategies of algebra in understandable terms. -- Zentralblatt fuer Didaktic der Mathematik

The innovative author of There Are No Electrons asked math professor Jim Loats to teach him algebra. The result is this wonderful book which explains the basic concepts, vocabulary and strategies of algebra. No exercises, just clear writing, humor and information. -- The Genius Tribe

The volume's easy pace and the use of a game as a metaphor probably will appeal to the casual learner. The book's gentle, conversational, gamelike approach may be sufficient to reach the 'unreachable.' -- Science Books and Films

From the Back Cover

"If you or anyone you know is frightened by algebra, then this entertaining, simply written book is an excellent way to overcome that fear. I know of no more painless way to master the basic concepts of algebra. Let's hope the authors will take up the challenge of a similar book about calculus!" Martin Gardner, author of The Night is Large

"I loved it!" Sheila Tobias, author of Overcoming Math Anxiety

"Ever read an algebra book for fun? Ever thought you would want to? Algebra Unplugged is just that sort of book- and innovative approach that does a great job taking the mystery and fear out of algebra. It's not a text book. You don't have to ever lift a pencil while reading it. Fascinating explanations of all the players in a first year algebra course. A must for anyone who is going to take algebra, dreaded it while taking it, or wants to brush up on it." Theoni Pappas, author of The Joy of Mathematics

"Algebra Unplugged is geared for the majority who are not good at math. Told with humor and understanding, it is an enjoyable book to read." Joan Harris, The Institute for Science and Society

"I very much enjoyed the book. A math book with lawyer jokes and stories of flogging tenors. It doesn't get any better than that." Thomas Seidenberg, Phillips Exeter Academy

"This book discusses algebra in a non-threatening, fun way." ERIC Clearinghouse for Science, Mathematics and Environmental Education.

More About the Author

After 89 Real Publishers rejected There Are No Electrons, I formed Clearwater Publishing Company to publish it myself. That was twenty years ago; the book has sold nearly 100,000 copies and continues to sell well. Thank you to everyone who has bought it.

Then I wrote two math books with Jim Loats, Ph.D.- Algebra Unplugged and Calculus for Cats. I also published my humorous novel, The Land of Debris and the Home of Alfredo. In answer to the hordes of people who ask me, hey, Kenn, how can I write better myself so I can live your cushy lifestyle, I published Joy Writing: Discover and Develop Your Creative Voice. Although, I must point out, I drive a 13 year old cargo van and camp in a 30 year old motor home. So "cushy" isn't the first word springing to most folks' minds about my lifestyle. But I do enjoy writing and that book describes my own philosophy about it.

While I was driving into the mountains, a voice whispered this sentence into my ear: "Some people say I ain't smart enough to have did what I done." The imaginary voice cracked me up. I spend so much time trying to write better, the idea of writing a book that was, at best, grammatically inconsistent seemed liberating and fun, only I had no idea for a story. When I got home, I tried to write in that voice and the result, a few months later, was "Jumper and the Bones." It's a sweet and sometimes funny little novel. I released it as a Kindle book and have gotten some really great feedback. But don't buy it if bad grammar irritates you. That's just how Jumper talks. I had not thought about the market, but it turns out that some kids enjoy the book at least as much as adults.

Over the last couple of years I started blogging, because everyone says authors "need" to blog. Once or twice a week I write about my tropical fish, or politics, or gardening. Sometimes I chat about writing or promoting books. My blog is called "The Wordguise Alembic;" predictably, I put together a collection of sixty or so blogs into a kindle book called "The Wordguise Alembic Volume One." Besides blogs and poems, it contains lengthy excerpts from each of my other published books, as well as chapters from two of my books in progress. It's an easy way to sample them all and choose which one you might like to read all the way through.

My little publishing venture has led me to meet many interesting folks, from famous guys like Dave Barry and Clive Cussler to folks as obscure as me. I've gotten neat letters from Ray Bradbury, Tom Robbins and a host of others, as well as from prisoners, folks in the White House, students and hopeful writers of all kinds. Writing introduced me to my tribe, and it's a cool bunch of people. I've had some fun surprises, as well. Famed inventor Dean Kaman was asked on the radio about his favorite books and he mentioned Calculus for Cats at some length. I discovered that Encyclopedia Britannica had recommended one of my math books. Once, at a bluegrass festival five hundred miles from home I saw someone in the audience reading Algebra Unplugged. I had to show them my driver's license to convince them I was one of the authors. At a lunch for local writers, I introduced myself to a guy whose eyes got wide as he shook my hand. "I've HEARD of you!" he said in astonishment. I do not, apparently, look like a guy someone might have heard of.

I also write songs and play guitar. I've performed on a few CD's and set my coffee cup down on even more. I was in the acoustic group "Cottonwood" for ten years or so; we released two CD's. Each included a few of my originals.

I like to garden, and when the harvest isn't so impressive, I let the plants go to seed, collect the seed, and try to convince my wife that's what I was going for all along. I harvest peaches from a half dozen trees I raised from seeds. I've recently gotten fascinated with growing mushrooms and have jars of mycelium lurking all around my office. I also make wine and soap and buttermilk, which is fun as long as you remember which one you're doing at any given time. I'm a defensive mechanic who will try to fix the problem that has stranded me at the side of the road for a long time before I call someone who knows what he's doing. Similarly, I will repair my own plumbing until my clothes are just too soaked, and will wire a light switch when asked to do so. I am rarely asked.

I've been married to my beautiful and very patient high school sweetheart for over 40 years now. We have three grown sons, a couple of cats, a bunch of guppies, and some banana slugs in a terrarium. I've been involved with a number of book-related non profits in Colorado, and served on the board of directors for a few. I'm nearly finished writing a book about ALS and Alzheimer's called "Revenge of the Pond Scum." I've written a half dozen unpublished novels and may release another one on Kindle just to see how that goes. But if you're listening, and your name is "Random House" I'd sure be willing to let you have a chance at them first.

5.0 out of 5 stars This algebra book turns Greek into plain English!, December 4, 1998
This review is from: Algebra Unplugged (Paperback)
Having made it through college in the 70's without taking a math course, I am now wanting to learn algebra. I took it in high school and I was great at memorizing formulas. I now want to know the basis of math and I started with Algebra.

Algebra Unplugged is the book that I have dreamed of. If I had this in high school I could have gone a long way. Every parent should buy it for their school age children and even read it themselves. It stresses concepts not formulas. It shows you why we do the things we do in algebra.

After having it a week, I was solving polynomial equations on a drink napkin while flying from back east.

Great book! Math teachers - have a bake sale and buy this for all of your students!

5.0 out of 5 stars Fantastic, helpful, and very readable book, January 18, 2002
By A Customer
This review is from: Algebra Unplugged (Paperback)
My main problem with algebra is that no one ever told me what it really is, besides a bunch of equations. I also couldn't understand why factoring was so important.

I'm happy to report that this book tells you what algebra is for and why factoring is important, and much more, and does do in a way that even the math-challenged can easily grasp. It also reassures the reader by saying that it's okay to need to read and reread the book to get a firm grasp on concepts. It is possibly the only math book I have ever read that didn't make me feel like an idiot, make giant assumptions, or skimp on the explanations. Although I don't think I will ever be close friends with math, this book makes it possible to negotiate an armed truce and (I hope) to succeed in college algebra after 10 years of doing no math more strenuous than balancing my checkbook.

The only drawback to this book is the embarrassing number of typos, but they detract only slightly from the text.

5.0 out of 5 stars Great help for relearning algebra, January 21, 2001
This review is from: Algebra Unplugged (Paperback)
This book, together with Practical Algebra, has bolstered my confidence, as I return to school after many years, for my MBA. Not having taken a math class in 30 years, my skills were beyond rusty. Algebra Unplugged is a light-hearted look at algebra concepts -- especially for the non-math majors among us -- and was a great start. I think I read through it in just a few days. The only problem for me was that it didn't contain any sample problems or self-tests, so I added Practical Algebra and that really helped.
