On my Homepage, look for the link \"Basic, Intermediate, and College Algebra: One Step at a Time.\" Choose \"Basic Algebra\", and look in \"Chapter 1\" for \"Sections 1.09 and 1.10.\" Here you will find my own non-traditional explanation that my own students used to find much easier to understand than most of the other textbooks being used. I also have lots of examples, exercises, and answers. In addition, most of the hardest problems are solved in color on the MATH IN LIVING COLOR pages that go with this topic.
