Why there are these different reviews
I had this book in freshman yr. as well as the geometry book that follows in sophmore yr of high school. In my own classes i often found that the people whom said bad things about the book such as those in the following reviews are the people who either did not pay attention in class, or did not care about the subject enough to put the effort to try to understand the matter. On the other hand, some of the concepts were a little advanced, but my teachers usually explained them in a way we could understand.If the student is doing their job as well as the teachers there shouldn't be a problem with this book. I would strongly recommend it.

BEST BOOK EVER
Don't listen to what the other people are saying. I got first hand experience on this book. I must say that this is probably the best and most easy to understand math book i have ever used. The answer key in the back allows the user to assure that their answers are correct. If you are considering buying this book, i must say YES, DEFINATELY BUY THIS BOOK, IT WILL BE WORTH YOUR WHILE!!!!

this is the most suckiest book i have ever read about algebra
this book sucks, it taught me nothing, because of this boook i faild algebra.

geometry key
Helpful to check students work.Package arrived on time in excellent condition.

From a student.
I had to use this book for a UW Independent Learing course because I failed the geometry course offered at my school. It is a great book for talented student that are planning to take more advanced math courses.
This is the Absolute Best Book Available in America Today
This book is extremely well thought out. The problems range from very accessible to very challenging. The book is thorough and teaches Geometry in the way that it should be taught, with a rich mathematical foundation and many opportunities for students of all abilities to learn to think criticlly. The Teachers' resource materials are excellent. There are two sets of tests, one more accessible and one more challenging. The Reteaching and Practice resource is an excellent source of class work handouts. To me this book is just as fine as the Algebra 1 book from the same series.To the best of my knowledge, this is the best book currently available in the United States. Students who are lucky enough to use this book, will be well prepared for standardized testing. ... Read more

Far better than most others
This is a well thought out Algebra textbook.I started teaching from it earlier this year and have grown to appreciate it very much.I am especially pleased the more I compare this to other books.Most math books these days are little more than pretty colors, crazy fonts, neat pictures, lots of distractions, and very little actual math instruction.This book, on the other hand, actually focuses on the math, explains it reasonably well, and has great sets of real example problems and practice problems of all difficulty levels, including lots of practical problems that aren't forced or contrived.It is not perfect, but it is the best I have seen.
Excellent book for students
This is a pretty good comprehensive textbook for students of all levels. There are twelve chapters in the book, plus a glossary, various helpful appendices, and an index. The book contains "A" (easy), "B" (intermediate), and "C" (challenging( problem sets for every topic covered. Also, enrichment topics are included, including "Extra," "Challenge," "Historical Note," "Application," and "Career."
GREAT
I picked this book up the other day and i thought it was really good. I like all the programs it tells you how to do. ... Read more

The only book you'll need.
I have taught elementary math for over 20 years, and have a master's degree in math education. I found this to be the best book on teaching basic concept of addition and subtraction I have ever had.There are numerous activities which require little preparation, group and individual activities, all of which will teach your students to understand the real meaning of the concepts and help them develop fluency with numbers that will make a significant difference in their futures with math.

A "Must Have" for Every Elementary Teacher
This Developing Number Concepts Book,along with the other two books in the Developing Number Concepts series, presents a complete number curriculum for kindergarten through third grade.This book, as well as the othertwo,are clearly written and extremely user friendly.This book,Additionand Subtraction,gives novice and experienced teachers a close look at whatthe teacher needs to know about teaching these operations.The activitiesare simple and require manipulatives and materials most teachers alreadypossess, yet at the same time are child centered and motivating.The"Analyzing and Assessing Children's Needs" section is anexcellent model for providing ongoing assessment in the classroom.Ibelieve these books are a must for every elementary teacher. ...

school supplies
Order arrived 2 days later than expected, but I was very pleased with the price I paid and the book was in excellent condition

Good In Some Ways; Weak In Others
Our school uses this book for all Geometry classes. The book is quite thorough, but serves the teacher more than the students. The students for the most part don't read it; just use it to find the assigned homework problems.
Weak Explanations and Fails to Challenge Even the Average High School Student
As a long time mathematics tutor and teacher I know this book very well. I don't think the material is presented or explained in a way that is especially helpful for young people. As a tutor I have to constantly reintroduce the topic and/or try to stay ahead of the student's class. Beyond that, the students are asked to do only the simplest of proofs. Additionally, a new topic will be introduced and then no problems appear in the exercise portion of the section to help the student test and practice his or her understanding of the newly introduced topic (and of course, those problems invariably will show up on the chapter exam and the final).

I was very pleased with the speed in which the item was delivered.The book was in perfect condition and my son needed it a.s.a.p.

Math Book
I needed this book for my daughter ASAP, and that's what I got, right on time.

Saved By Amazon
After my son's book was missing over a period, I thought I would have to pay another $90-$100's mid-way through the school year. I ordered this "used" book. It came on time. It was in perfect condition and I was truly overjoyed. Thanks to the sellers, shippers and amazon. ... Read more

Editorial Review

Young Robert's dreams have taken a decided turn for the weird. Instead of falling down holes and such, he's visiting a bizarre magical land of number tricks with the number devil as his host. Starting at one and adding zero and all the rest of the numbers, Robert and the number devil use giant furry calculators, piles of coconuts, and endlessly scrolling paper to introduce basic concepts of numeracy, from interesting number sequences to exponents to matrices. Author Hans Magnus Enzensberger's dry humor and sense of wonder will keep you and your kids entranced while you learn (shhh!) mathematical principles. Who could resist the little red guy who calls prime numbers "prima donnas," irrational numbers "unreasonable," and roots "rutabagas"? Not that the number devil is without his devilish qualities.He loses his temper when Robert looks for the easy way out of a number puzzle or dismisses math as boring and useless. "What do you expect?" he asks. "I'm the number devil, not Santa Claus." (Ages 10 to adult) Read more

One of the best children's books ever
This is without question one of the best children's books with a mathematical theme ever written. It is witty, charming and fun for children and actually teaches them some mathematics along the way. Not just the simple math of one and one is two; very complex ideas such as infinity, Fibonacci numbers, and Pascal's triangle are described in ways that elementary school children can understand. I couldn't put it down as I read through and marveled at the ability of the author to explain these mathematical concepts.
Wonderful story
This is a great book for everyone.My son 7, who is very interested in math loved it.The only drawback is the use of words like rutabaga instead of square root, unreasonable numbers instead of irrational munbers etc.If your child can live with that, this is a great learning tool.The dreams are cute fantasies.A nice way to incorporate math into a fictional book.I would recommend it for about 4th -6th grade, or younger if your child is particularily interested in math.

Awesome [and educational] book!
When I first got this I thought was going to be very boring because it's about math. But once I started reading it I couldn't get my eyes off of it! It teaches different tricks to work out math problems in a fun way. If you or your kids are struggling in some areas in math as well as trying to find an entertaining book to read this is the perfect book. ... Read more

Not as inexpensive as you would think
I shopped around a lot before I purchased this book from a used book dealer.I needed more than one, so I had to shop around.I ended up buying more than a few.These books are in excellent shape, no highlighting, no writing in the books, and fantastic bindings.The base price was less than most of the prices in the Amazon listing.Even the publisher's price for a NEW book was less than most of the listings in Amazon.I find it sad that folks are selling books with higher prices than the publisher is charging for a new one.

Not bad
The real trouble with Algebra and Precalculus is that many of the topics are interchangable.This book does a fairly good job of covering many different topics.I wish some of the examples were a little better, but there a lot of solutions and answers in the back for the many problems at the end of a section.I think ideally, an Algebra II course should be very skill based, focused on "solving for x" in various situations.A little more concrete and a little less analytical.A precalculus course should be focused more on functions and function analysis.Also it should include trigonometry and topics typically covered in a calculus course (without differentiation or integration) such as polar coordinates, parametrics, and vectors.

Algebra 2 textbook
I purchased the book with the intention of teaching myself all the core material in it. The material offers readers a limited number of examples per chapter per section. While these examples may sometimes make you wish for added detail, ultimately there is enough explanation to pull the reader through. Be sure you understand the previous chapter before moving onto the next or you will most likely get lost. In the end I was very satisfied with my order. Listen to me...if your at least decent in math you'll do just fine following this Algebra 2 textbook! ... Read more

Awesome Algebraic Resource
This is simply a must have for any student or homeschooling parent today.Basically, it's the dictionary of the mathematic world.It's simple, concise, and indispensable.It's full of easy to find formulas, without all the mess to confuse you.If you're stuck on algebra, this is the book for you.

A recommendation from an algebra teacher!
For the last three or four years, I have recommended this book to my students' parents.I teach algebra (grade 8) and pre-algebra (grades 7 and 8) and have found that his book is written in a non-threatening, easy to understand manner.It is a perfectly wonderful reference book.Math is scary enough...this book demystifies algebra.Love it!

Algebra to Go
This is the best reference handbook that parents and teachers will fine it useful for students. Algebra to Go, "demystifies algebra for students in 8 grades and up by explaining key and often complex math topics in a way that's clear, friendly, and understandable". It is also a great refresher for parents who may have forgotten a thing or two about Algebra.. ... Read more
