Watch online video lessons and learn about the different aspects of matrices and absolute value. The dynamic animations and graphics help you quickly retain critical info.

Matrices and Absolute Value - Chapter Summary and Learning Objectives

Matrices are number grids that serve as the basis for linear mathematics. Absolute values are how far a number is from zero no matter if the number is positive or negative. Our instructors show you how matrices are used in mathematics as well as explain how absolute values are important. In addition to our video lessons, you will find quizzes that help you determine your progress for understanding matrix and absolute value concepts. This chapter is designed to teach you how to:

• Take a determinant of a 2x2 matrix
• Graph an absolute value
• Evaluate complicated absolute value equations
• Explain why matrices and absolute values are useful
