Question

Find the value of each expression.

50. $\mathbf{8}\mathbf{+}\left(\mathbf{-}\mathbf{5}\right)$

Short answer

The valueof $8+\left(-5\right)$ is 3.

Step-by-step solution

– Description of step.

Write 8 as $3+5$ into $8+\left(-5\right)$.

$3+5+\left(-5\right)$

– Inverse property.

For any real number $a$, $a+\left(-a\right)=0=\left(-a\right)+a$.

– Apply inverse property.

Apply inverse property to the expression in step 1 and simplify.

$3+0=3$

Therefore, the value of $8+\left(-5\right)$is 3.
