Using FOIL and other products
Solving linear and absolute value equations
Dealing with inequalities
The nice thing about the rules in algebra is that they apply no matter what level of mathematics or what area of math you’re studying. Everyone follows the same rules, so you find a nice consistency and orderliness. In this chapter, I discuss and use the basic rules to prepare you for the topics that show up in Algebra II.
