Is it possible to add B + F?

• Yes, because the number of columns are the same in both matrices

• No, because there is negative element in matrix B

• No, the matrix sum is undefined because matrix B and F do not have the same dimensions

• Yes, because the number of columns of matrix B matches the number of rows of matrix F

Find the product of the two matrices.
