You may want to see my FREE website for a non-traditional explanation on this topic.  The easiest way to find the website is to use the easy-to-remember and easy-to-spell link www.mathinlivingcolor.com.  Near the bottom of this page is a link that takes you to my Homepage.  


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 "Section 1.11 Inequalities."  I think you will really like the "Math in Living Color" pages that go with this section.
