For example, to find the entry in row 4 and column 3 of the matrix you get out of the product, you take all the entries in the fourth row of the first matrix, all the entries in the 3rd column of the second matrix, multiply those lists together in the way you were talking about in your comment, and then add up all those multiplications.
