Answer:
1. -a + b = depends on which integer is bigger, if b is bigger than a, then it would be positive. If -a is bigger, then it will be negative
2. a-(-b) = positive
3. -a * b = negative
a. 87 + 65 b. -58+42
c. 73+(-55) d. -47+(-30)
Step-by-step explanation:
Remember:
two positives(multiply or divide) = positive
two negatives(multiply or divide) = positive
a positive and a negative(multiply or divide) = negative
two positives(addition) = positive, (subtract) = depends on which integer is bigger
two negatives(addition) = positive, (subtract) = depends on which integer is bigger
