Question

$$- \frac { 1 } { 2 } [ 78 - ( - 78 ) \times 2 ]$$

Evaluate

$-117$

Solution Steps

Multiply $-78$ and $2$ to get $-156$.

$$-\frac{1}{2}\left(78-\left(-156\right)\right)$$

The opposite of $-156$ is $156$.

$$-\frac{1}{2}\left(78+156\right)$$

Add $78$ and $156$ to get $234$.

$$-\frac{1}{2}\times 234$$

Express $-\frac{1}{2}\times 234$ as a single fraction.

$$\frac{-234}{2}$$

Divide $-234$ by $2$ to get $-117$.

$$-117$$
