# Ch 21: Working with Matrices & Determinants

With these lessons, students can learn more about the tools they will need to enhance their high school precalculus skills. Working with this chapter can help students study for upcoming exams, prepare for discussions in class, and earn higher grades.

## Working with Matrices & Determinants - Chapter Summary

High school students need to read and understand a great deal of information both before they graduate and as they move on in college or the professional world. This chapter provides students with focused training on developing their understanding of matrices and determinants.

Instead of an endless chapter of information, the chapter has been divided into short, individualized lessons. Students have the option to review all of the lessons in order, but they can also pick and choose lesson topics in which they need the most assistance. The chapter menu provides a list of all lessons available, and since each lesson is only focused on a single topic, students can easily find what they need. After completing this chapter, students will be ready to:

• Solve inverse matrices
• Solve linear systems using Gaussian and Gauss-Jordan elimination
• Solve inconsistent and dependent systems using Gaussian elimination
• Use determinants to solve systems of linear equations in two and three variables
• Use Cramer's Rule with inconsistent and dependent systems
• Evaluate higher-order determinants in algebra
