Answer:
for question 5 the answer is 0.
for question 6 the answer is -34.

Explanation:
question 5: -17+20 can also be written as 20-17 which is equal to 3. Next, we have to add 3 with -3. 3+(-3) is the same as 3-3 which equals 0.
question 6: 25-25 = 0, and the remainder is -34.
question 9: 7-11 can also be written as -11+7, which is equal to -4.
