-8 and +8 equal 0 since they cancel out. It's basically 8-8. So that leaves you with 0-(-7). The two negatives make a positive, now you're left with 0+7=7. Your answer is 7. Hope this helps :)

6 7/8. You must get a common denominater. I used 8, which multiplis 4 times 2. Then the top number is multiplied by 2 to get 2/8. Now add the tops and bottoms to get 7/8. Now add the whole numbers to get 6.
