    Directions:

    Select AB or BA and solve in step by step fashion.

    The product of two matrices can be computed by multiplying elements of the first row of the first matrix with the first column of the second matrix then, add all the product of elements. Continue this process until each row of the first matrix is multiplied with each column of the second matrix.

    Beautiful. Easy stuff. No wonder it is taught at the precalculus level. Don't worry. I will not post complicated linear algebra material. Simply, I am not there yet.
