Question

Find the value of $\left(-10–10\right)÷\left\{-10-\left(-10-10\right)\right\}$

Answer 1

Compute the given expression

Given expression is $\left(-10–10\right)÷\left\{-10-\left(-10-10\right)\right\}$

$$\begin{gathered} \therefore \left(-10–10\right)÷\left\{-10-\left(-10-10\right)\right\}=\left(-20\right)÷\left\{-10-\left(-20\right)\right\} \\ =\left(-20\right)÷\left(10\right) \\ =-2 \end{gathered}$$

Hence the required value is $-2$
