## Overview

With Barron’s, learning algebra becomes fun. Painless Algebra defines algebraic terms, shows students how to avoid pitfalls in calculation, presents painless methods for understanding and graphing equations, and makes problem-solving fun.

Geared toward middle school– and high school–level learners, Painless Algebra takes a lighthearted, humorous approach to learning vocab and is ideal for students who find it confusing, or who just need a little extra help.

Students can test their learning progress with quizzes and “Brain Ticklers”, plus additional games online to challenge students, including Beat the Clock, a line match game, and a word scramble.

The authors' main goal is to clear up confusion and pique interest by emphasizing the intriguing and often exciting ways in which students can put each subject to practical use.

The book will help middle school students, high school students, or even adults looking to sharpen their math skills. I got this book so my brain wouldn't turn to mush over my long school vacation. I recommend this book to pre-algebra students or excel algebra students like myself. It's quick, easy, and really painless!

This book is a wealth of information and very easy for people to read. I have never taken Algebra in school and find that I am picking up on it easly and quickly. The only problem I have found is that there aren't enough 'Brain Ticklers' Math problems at the end of each subject to help you get used to what you are already doing before moving on to the next subject.Moreover, there are no formulas in the answer section to show how they came to that answer, which presents a problem when you get an answer wrong it is very hard to find out where you made a mistake without rereading the whole section over.Even then, sometimes you still can't find out where you made the mistake and must continue on with the book in hopes that it doesn't present a problem for you later.

I bought this so I could help my daughter with her upcoming Algebra class. I'd taken Algebra many years ago but had forgotten almost all of if. I found the book to be easy to follow and to-the-point. It's exactly what I was looking for.

Easy-to-read, fun format.  Well structured to build on concepts as presented.  One caveat:  taking a square root of a negative number IS defined.  Early on, dividing by zero is properly presented as &quot;undefined.&quot;  Unfortunately, in the ROOTS section, the term &quot;undefined&quot; is used to describe taking a square root of a negative number.  The biggest example of &quot;defining&quot; a concept is where imaginary numbers came from -- by definition, the square root of -1 is &quot;i&quot; usually represented by a lower-case script letter.  One of the best treatments of that in a book catering to this level of a learner was &quot;We'll talk about that later&quot; rather than insetting an absolute that will have to be &quot;unlearned&quot; some time in the future.  Not a deal-breaker, as otherwise the book rocks.

I'm the type that breaks into a cold sweat at the mention of the word Algebra. Until now! I picked this book up the other day to help me with an Algebra class and it FINALLY all makes sense to me. Very clear, very easy, very very very straight forward. I'm so grateful for this book and recommend it highly. I even created an account on B&N just so I could write this review, I think that highly of it.

Painless Algebra really was painless. I used it with my son for Pre-Algebra just before high school. It provided a good foundation for Algebra 1. It was also painless for me, the parent, whose been out of school for many years!

This is an excellent resource for middle school students. It is written with the student in mind and has example problems that students can test themselves on. It's written clearly and it is handy to carry around in a backpack. It can also help parents refresh their memory. I call it a must buy for any middle school and high school student.

I found this book very hard to understand. It wasn't clear and it was very confusing. I had to reread it several times but still I didn't get it. The chapters were much too short and didn't include everything I needed. I can't believe it's called 'Painless' when it really is more 'Painful'!
