if \(M=\left(\begin{array}{ccc}1 & 2 & 3 \\ -1 & -3 & -2 \\ 0 & 1 & 0\end{array} \right)\)
find the determinant of matrix \(M\)

Two matrices \(\mathbf{M}\) and \(\mathrm{N}\) are defined by \(M=\left(\begin{array}{ccc}3 & 2 & 1 \\ 4 & 1 & 1 \\ -1 & 2 & 0\end{array} \right) \quad\) and \(\quad N=\left(\begin{array}{ccc}2 & 0 & 1 \\ 3 & -2 & 2 \\ 4 & -4 & 3\end{array} \right)\)
