Question

Find the value of each expression.

 

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

Step-by-Step Solution

Answer

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

Step 1 – Description of step.

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

 

$-2+2-10$

Step 2 – Inverse property.

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

Step 3 – Apply inverse property.

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

$0-10=-10$

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