# Ch 19: ACT Math: Matrices

Get ready to shine on the math section of the ACT college admissions test. Use our entertaining video lessons and quick quizzes to review crucial algebraic concepts.

## ACT Math: Matrices - Chapter Summary

Matrices are a fundamental aspect of the linear algebra branch of math. In this chapter, review the following basic information through our motivating videos:

• Definition of matrix
• How and why matrices are used
• Parts of a matrix: rows, columns and brackets
• Adding, subtracting and multiplying matrices
• Taking determinants of matrices

Go over all of the information about matrices so that you can demonstrate proficiency on the ACT math test. View concise examples of matrices in the lessons, and take the follow-up quizzes to see how you're doing.

### ACT Math Objectives

The ACT test speaks to the three mathematical areas of algebra, geometry and trigonometry. The exam considers algebra as three levels: pre-, elementary and intermediate. Overall, the algebra section involves 55% of the 60-question test. Our review lessons, followed by self-assessment quizzes, will help you revisit the key concepts necessary for the ACT. The test's pre-algebra questions assume a base built upon an understanding of fundamental linear algebra skills. The exam then checks for more in-depth understanding of the intermediate skills directly related to matrices.

You'll have 60 minutes to complete 60 multiple-choice math problems. You can complete all of the questions without the use of calculators. However, you'll be able to use certain approved models of calculators, if you wish to do so. Check with the ACT student site for details concerning calculator use.

Your score report will include four scores for the math portion of the test: an overall score on all 60 questions and sub-scores for pre-algebra/elementary algebra, intermediate algebra/coordinate geometry and plane geometry/trigonometry.
