We can use the numpy. add and numpy.subtract functions to add and subtract atrices in Python as in the following code, which follows from the preceding code: # Add A and B print (numpy. add (A,B)) # Subtract A and B print (numpy. subtract (A,B)) 122 Computational Algorithms in Linear Algebra The code has the following output: [[ 4 3 3] [17 4 2] [ 3 4 4]] [[ 2 1 -1] [ 1 -4 0] [ 3 4 -2]] Of course, this is in fact A + B and A- B, which we could find by hand if we add and subtract all the numbers in the matrices element by element. Next, we continue with more arithmetic of matrices: multiplying a whole matrix by a scalar (or, by a number).
