Algebra 2

Introduction to Matrices defines Matrices and their elements, and demonstrate how they are used to organize data. Matrices are much more powerful than simple organizational tools. You can perform operations with matrices just like you can with numbers. You will learn the steps involved in Adding and Subtracting Matrices and even learn about Matrix Multiplication. You will explore the Commutative Property of Matrices and Associative Properties of Matrices, which can help you when Solving basic Matrix Equations.
