Full Description

You, too, can understand algebra-just ask Dr. Math??!

Getting ready to take your first algebra class? Don't panic. Making the leap from the concrete world of numbers and real objects to the abstract world of letters and symbols doesn't have to be as scary as it sounds. Dr. Math??-the popular online math resource for students, parents, and teachers-is here to help!

Students just like you have been turning to Dr. Math for years asking questions about math problems, and the math doctors at The Math Forum have helped them find the answers with lots of clear explanations and helpful hints. Now, with Dr. Math Gets You Ready for Algebra, you'll learn just what it takes to succeed in this subject. You'll find the answers to dozens of real questions from students who needed help understanding the basic math concepts in a typical pre-algebra class. You'll learn all about basic algebraic operations and their connections to the real world. Pretty soon, everything from integers to single-variable equations will make sense. Plus, you'll get plenty of tips for working with tricky problems.

You won't find a better introduction to the world and language of algebra anywhere!
