Determinant of $$$\left[\begin{array}{c}3\end{array}\right]$$$

The calculator will find the determinant of the square $$$1$$$x$$$1$$$ matrix $$$\left[\begin{array}{c}3\end{array}\right]$$$, with steps shown.

Calculate $$$\left|\begin{array}{c}3\end{array}\right|$$$.

The determinant of a 1x1 matrix is $$$\left|\begin{array}{c}a\end{array}\right| = a$$$.

$$$\left|\begin{array}{c}3\end{array}\right| = 3$$$

$$$\left|\begin{array}{c}3\end{array}\right| = 3$$$A
