3.5 Perform Basic Matrix Operations Add Matrices Subtract Matrices Solve Matric equations for x and y

Key Vocabulary: Matrix: Dimensions: Elements: Equal: Scalar: Scalar Multiplication:

Dimensions and Elements Name the dimensions of the matrices and how many elements are in each matrix. Ex:

Adding and Subtracting Matrices To add or subtract matrices, simply add or subtract elements in corresponding positions. Add two matrices together:

Subtract two matrices:

Multiply a Matrix by a Scalar Scalar: a real number used to multiply to each element in the matrix. Ex:

Solve a Matrix Equation: Step 1: Identify the variables in the matrices. Step 2: Set up equations using elements in corresponding positions from all the matrices. Step 3: Solve the equation for the variable. Ex:
