$$\begin{bmatrix} 1 && 5 \\ 6 && 1 \\ -2 && -4 \end{bmatrix} * \begin{bmatrix} 0 && 3 \\ -6 && 4 \end{bmatrix} \\~\\ = \begin{bmatrix} 1*0+5*-6 && 1*3+5*4 \\ 6*0+1*-6 && 6*3+1*4 \\ -2*0+-4*-6 && -2*3+-4*4 \end{bmatrix} \\~\\ = \begin{bmatrix} -30 && 23 \\ -6 && 22 \\ 24 && -22 \end{bmatrix}$$

helped refresh my memory on these..maybe it can help you too :)
