More questions on the Math 1 test fall under the broad category of algebra than any other topic: approximately 30% of the questions are strictly algebraic. Several other questions that the College Board would assign to other categories, such as geometry, functions, and trigonometry, require the use of the algebra that you will review in this chapter.
It is very important to stress that many algebra questions can be answered using one of the tactics and strategies discussed in Chapter 1, “Important Tactics.” If, while taking the Math 1 test or a practice test in this book, you get stuck on an algebra question, you should use one of those tactics rather than skip the question. In this chapter, however, you will review the correct mathematical way to handle these questions.
