Question

Determine the product:

$\left(-2\right)\times 35\times \left(-5\right)$

Answer 1

$$\begin{gathered} \left(-2\right)\times 35\times \left(-5\right)\left[\left(-\right)\times \left(+\right)=\left(-\right)\right] \\ =-\left(2\times 35\right)\times \left(-5\right) \\ =\left(-70\right)\times \left(-5\right)\left[\left(-\right)\times \left(-\right)=\left(+\right)\right] \\ =350 \end{gathered}$$

Hence, the product is $350$
