** Math XL:**
We encourage students who want to refresh their knowledge of Math 89, 90, or 91 before taking an exit exam to use the online homework system MathXL.
With MathXL, you can practice homework problems, check your answers, see example problems, watch instructor videos, and view the relevant pages from the textbook.

If you purchased a new textbook from the bookstore for one of those classes within the past 12 months, then you received a MathXL access code with the book. Otherwise, you can purchase one online at www.mathxl.com.

Once you purchase an access code, you'll need to register with MathXL and then sign up online for the appropriate course. To do that you'll need the following CourseID:

Math 89 XL12-31YP-701Y-5GS2Math 90 XL12-31ZL-001Y-7GS2

Math 91 XL12-31ZQ-101Y-2GS2

For Math 91, please note that MathXL does not yet have problems on “counting methods.” See below for ideas on how to study for those types of problems.

** Textbook:**
You can also study for the Math 89, 90, or 91 exit exams by practicing homework problems from the course textbook. (Actually, any book on Beginning and
Intermediate Algebra should contain most or all of these topics. The campus library has many books on Beginning and Intermediate Algebra.)

For Math 89, the textbook is

*Beginning Algebra*, Second Custom Edition for CSULA, ISBN-10: 1-256-67969-0, ISBN-13: 978-1-256-67969-1. This custom edition was created by taking chapters from the book
