To add or subtract 2 or more matrices, they have to be in the same dimensions
The dimensions of a matrix are
The number of rows m and the number of column n
It is m x n
So the matrix of dimensions 4 x 5 has m = 4 and n = 5
The dimensions 5 x 3 means m = 5 and n = 3
Number of rows not equal
Number of columns not equal
Then we can NOT add them
The answer is NO
