Question

Evaluate each of the following:

a.$15-\left(-8\right)=\_\_\_$

b. $-8+\left(-22\right)=\_\_\_\_$

c. $4\times \left(-2\right)+6=\_\_\_$

Short answer

a. The answer is $15-\left(-8\right)=$$23$.

b. The answer is $-8+\left(-22\right)=$$-30$.

c. The answer is$4\times \left(-2\right)+6=-2$.

Step-by-step solution

Part (a) step 1: Given Information 

We need to evaluate$15-\left(-8\right)=\_\_\_\_$.

Part (a) step 2: Simplify 

$15-\left(-8\right)=15+8=23$

Part (b) step 1: Given Information 

We need to evaluate$-8+\left(-22\right)=\_\_\_\_$.

Part (b) step 2: Simplify

$$\begin{gathered} -8+\left(-22\right)=-8-22 \\ =-30 \end{gathered}$$

Part (c) step 1: Given Information 

We need to evaluate$4\times \left(-2\right)+6=\_\_\_$.

Part (c) step 2: Simplify

$$\begin{gathered} 4\times \left(-2\right)+6 \\ =-8+6 \\ =-2 \end{gathered}$$
