Question

Determine the product

$\left(18\right)\times \left(-185\right)\times \left(-4\right)$

Answer 1

$$\begin{gathered} \left(18\right)\times \left(-185\right)\times \left(-4\right)\left[\left(+\right)\times \left(-\right)=\left(-\right)\right] \\ =-\left(18\times 185\right)\times \left(-4\right) \\ =\left(-3330\right)\times \left(-4\right)\left[\left(-\right)\times \left(-\right)=\left(+\right)\right] \\ =13320 \end{gathered}$$

Hence, the product is $13320$
