Matrices a and b are Pandas dataframes. Use the .head() method on each of them to view them.
Work out the product of these two matrices on your own.
Enter the values of the product of the a and b matrices into the product array, created using np.array().
Use the validation on the last line of code to evaluate your estimate. The .dot() method multiplies two matrices together.
