Question

Evaluate each of the following:

a.$-11-\left(-9\right)=\_\_\_$.

b.$34+\left(-55\right)=\_\_\_$.

c.$\frac{-56}{8}=\_\_\_$.

Short answer

a. The answer is$-11-\left(-9\right)=-2$.

b. The answer is$34+\left(-55\right)=-21$.

c. The answer is$\frac{-56}{8}=-7$.

Step-by-step solution

Part (a) step 1: Given Information 

We need to evaluate$-11-\left(-9\right)=\_\_\_$.

Part (a) step 2: Simplify

$11-\left(-9\right)=-11+9=-2$

Part (b) step 1: Given Information 

We need to evaluate$34+\left(-55\right)=\_\_\_$.

Part (b) step 2: Simplify

$34+\left(-55\right)=34-55=-21$

Part (c) step 1: Given Information 

We need to evaluate$\frac{-56}{8}=\_\_\_$.

Part (c) step 2: Simplify

$\frac{-56}{8}=-7$
