The product of the matrix is .

Step 1:

Multiply the numbers in the first row of the first matrix by the numbers in the first column of the second matrix, add the products, and put the result in the first row, first column of the matrix.

.

Step 2:

Follow the procedure as step1 using the second row of the first matrix and first column of the second matrix, write result in the second row,  first column of the matrix.

.

Step 3:

Simplify the product matrix.

.

The simplified product matrix is .
