Ask any professional and you'll be told that the one requirement for becoming an expert is practice, practice, practice.
We give you lots of practice!
There are Practice exercises for each concept or skill. Having difficulty with any of them? The green arrow tells you what problem with a worked-out solution to revisit in the lesson.
In the Apply section, you apply the concepts or skills to different situations or contexts.
You can test your knowledge using the Self-Quiz for each lesson at PowerAlgebra.com .
