Heart of Algebra centers on the linear function and other information covered in a typical high school Algebra I class. To answer SAT math questions in this area, you’ll need to feel comfortable working with the following:

 Evaluating, simplifying, and factoring algebra expressions (Chapter 3)

 Solving algebra equations and inequalities (Chapter 4)

 Working with linear functions in four complementary ways: words, tables, graphs, and equations (Chapter 5)

 Solving systems of equations (both linear and non-linear), and identifying when such systems have either no solution or infinitely many solutions (Chapter 6)

In Part 2, I cover all these topics in depth.
