Question

Choose the correct answer and Fill in the blanks:

$\_\_\_-\left(-8\right)=\left(-10\right).\left[\left(-18\right)/\left(+18\right)\right]$

Answer 1

If we substitute $-18$ we get

$$\begin{gathered} \left(-18\right)+\left(-8\right) \\ -18+8 \\ =-10 \end{gathered}$$

Hence, $\left(-18\right)-\left(-8\right)=-10$
