Question

Calculate the value of each of the following expressions.

$a+\left(-b\right)$, where $a=-35$ and $b=-75.$

Answer 1

The value of $a+\left(-b\right)$ where $a=-35$ and $b=-75.$

$$\begin{gathered} a+\left(-b\right)=a-b \\ =\left(-35\right)-\left(-75\right) \\ =\left(-35\right)+75 \\ =40 \end{gathered}$$

Hence, the value is $40.$
