Write the multiplication of first row of first matrix and each column of second matrix and perform addition between the multiplications to form the first row of product matrix.

$\left[\begin{array}{cc}4â‹\dots 6+0â‹\dots (−2)& 4â‹\dots 4+0â‹\dots 1\end{array}\right]$

Write the multiplication of second row of first matrix and each column of second matrix and perform addition between the multiplications to form the second row of product matrix.

$\left[\begin{array}{cc}4â‹\dots 6+0â‹\dots (−2)& 4â‹\dots 4+0â‹\dots 1\\ (−3)â‹\dots 6+7â‹\dots (−2)& (−3)â‹\dots 4+7â‹\dots 1\end{array}\right]$

Write the multiplication of third row of first matrix and each column of second matrix and perform addition between the multiplications to form the third row of product matrix.
