Question

Find the value of each expression.

$\mathbf{-}\mathbf{2}\mathbf{-}\mathbf{8}$

Short answer

The value of $-2-8$ is $\mathbf{-}\mathbf{10}$.

Step-by-step solution

– Description of step.

Write $-8$ as $2-10$ into $-2-8$.

$-2+2-10$

– 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.

$0-10=-10$

Therefore, the value of $-2-8$ is $-10$.
