b. $34 + (- 55) =_$ .
c. $\frac{- 56}{8} =___$ .

Short Answer

Expert verified

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

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

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

Step by step solution

Part (a) step 1: Given Information

We need to evaluate $- 11 - (- 9) =___$ .

Part (a) step 2: Simplify
