a. $15 - (- 8) =_$
b. $- 8 + (- 22) =$
c. $4 \times (- 2) + 6 =_$

Short Answer

Expert verified

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

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

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

Step by step solution

Part (a) step 1: Given Information

We need to evaluate $15 - (- 8) =____$ .

Part (a) step 2: Simplify

$15 - (- 8) = 15 + 8 = 23$

Part (b) step 1: Given Information

We need to evaluate $- 8 + (- 22) =____$ .

Part (b) step 2: Simplify

$- 8 + (- 22) = - 8 - 22 = - 30$

Part (c) step 1: Given Information

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

Part (c) step 2: Simplify

$4 \times (- 2) + 6 = - 8 + 6 = - 2$
