Matrix 1
+
Matrix 2
In the case of matrix addition, the order in which matrices are added is not important therefore Matrix 1 + Matrix 2 = Matrix 2 + Matrix 1.
Result
The addition is accomplished by addition of corresponding elements. The matrix addition is commutative because of ordinary addition is being done on the corresponding elements of the two matrices and both should have same dimension means both should have same number of columns and rows.
