Determinant (3x3) Sarrus' Rule - Matrix to Equation

Question

Using Sarrus' rule, which equation gives the determinant of this matrix?

$$\left[ {\begin{array} {ccc}  4 &  -2 &  -8 \ -3 &  7 &  -2 \ -3 &  0 &  6 \end{array}  } ight]$$

Accepted Answer

$$\begin{array}{l} (4 \cdot 7 \cdot 6) + (-2 \cdot -2 \cdot -3) + (-8 \cdot -3 \cdot 0) \ - (-8 \cdot 7 \cdot -3) - (4 \cdot -2 \cdot 0) - (-2 \cdot -3 \cdot 6) \end{array}$$

Answer

$$\begin{array}{l} (4 \cdot 7 \cdot 6) + (-3 \cdot 0 \cdot -8) + (-3 \cdot -2 \cdot -2) \ - (-3 \cdot 7 \cdot -8) - (4 \cdot 0 \cdot -2) - (-3 \cdot -2 \cdot 6) \end{array}$$

Answer

$$\begin{array}{l} (4 \cdot 7 \cdot 10) + (-2 \cdot -2 \cdot -3) + (-8 \cdot -3 \cdot 0) \ - (-8 \cdot 7 \cdot -3) - (4 \cdot -2 \cdot 0) - (-2 \cdot -3 \cdot 10) \end{array}$$
