Adding and Subtracting Matrices
❖ This tutorial video provides a basic introduction to Adding and Subtracting Matrices. Also, this video contains many examples and practice problems on Addition and Subtraction of Matrices.
❖ Any matrix can only be added (subtracted) to another matrix if the two matrices have the same size (dimension, order).
❖ To add two matrices, just add the corresponding entries, and place this sum in the corresponding position in the matrix which results.
So, any matrix can only be added to another matrix if
The size of the 1st matrix = The size of the 2nd matrix
Otherwise, the answer will be undefined.
❖ The number of rows and columns that a matrix has is called its size, its order, or its dimension.
❖ In this video, we will learn:
