# Algebra Review

Printer-friendly version

Knowledge of the following mathematical operations is required for STAT 200:

• Subtraction
• Division
• Multiplication
• Radicals (i.e., square roots)
• Exponents
• Summations  $$\left( \sum \right)$$
• Factorials (!)

Additionally, the ability to perform these operations in the appropriate order is necessary.Follow the links below to work through a quick review of order of operations, summations, and factorials along with a self assessment for you to complete on your own.  Use these materials to check your understanding and preparation for taking STAT 200.

We want our students to be successful!  And we know that students that do not possess a working knowledge of these topics will struggle to participate successfully in STAT 200.

### Review Materials

Are you ready?  As a means of helping students assess whether or not what they currently know and can do will meet the expectations of instructors of STAT 200, the online program has put together a brief review of these concepts and methods.  This is then followed by a short self-assessment exam that will help give you an idea if this prerequisite knowledge is readily available for you to apply.

Self-Assessment Procedure

1. Review the concepts and methods on the pages in this section of this website.

2. Download and complete the Self-Assessment Exam.

3. Review the Self-Assessment Exam Solutions and determine your score.

Your score on this self-assessment should be 100%!  If your score is below this you should consider further review of these materials and are strongly encouraged to take MATH 21 or an equivalent course.

If you have struggled with the methods that are presented in the self assessment, you will indeed struggle in the courses above that expect this foundation.

Please Note:  These materials are NOT intended to be a complete treatment of the ideas and methods used in algebra . These materials and the self-assessment are simply intended as simply an 'early warning signal' for students.  Also, please note that completing the self-assessment successfully does not automatically ensure success in any of the courses that use these foundation materials.

Please keep in mind that this is a review only. It is not an exhaustive list of the material you need to have learned in your previous math classes. This review is meant only to be a simple guide of things you should remember and that are built upon in STAT 200.
