ADDING AND SUBTRACTING MATRICES
Addition or subtraction of two matrices can be done by simplifying the corresponding terms in the matrix.
Note :
If the order those matrices are not same, then we cannot add those matrices.
Example of Addition of Two Matrices
Add the following matrices.
Solution :
Step 1 :
Grouping the corresponding terms.
Step 2 :
Simplify the corresponding terms.
Step 3 :
The simplified matrix is the result.
Example of Subtraction of Two Matrices
