Question

Choose the correct answer and fill the blank for$-1\times (-2)\times (-10)=\_\_\_\_\_$

• A. $-20$
• B. $20$

Answer 1

The correct option is A

$-20$

For solving $(-1)\times (-2)\times (-10)$

On multiplying $$\begin{gathered} -ve\times (-ve)=+ve \\ +ve\times (-ve)=-ve \end{gathered}$$

So$-ve\times -ve\times -ve=-ve$

So on multiplying $-1$ by $-2$ we get $+2$

On multiplying $+2$by $-10$ we get $-20$ an answer

So the answer$(-1)\times (-2)\times (-10)$$=$ $-20$
