Question

Evaluate the following: $\left(-31\right)÷\left[\left(-30\right)+\left(-1\right)\right]$

Answer 1

Determine the value of $\left(-31\right)÷\left[\left(-30\right)+\left(-1\right)\right]$.

$\begin{array}{rcl}\left(-31\right)÷\left[\left(-30\right)+\left(-1\right)\right]& =& \left(-31\right)÷\left[-30-1\right]\\ & =& \left(-31\right)÷\left(-31\right)\\ & =& \frac{-31}{-31}\\ & \Rightarrow & \left(-31\right)÷\left[\left(-30\right)+\left(-1\right)\right]=1\end{array}$

Hence, the value is $1$.
