Answer by ReadingBoosters(3246) (Show Source): You can put this solution on YOUR website!
What sign is between the 7 and the 9?????
....
Start with the parentheses
...
3 + -1 = 2
...
Then multiplication
9*2 = 18
...
2*5 = 10
...
Then addition
5 + -5 = 0
So without knowing what is between 7 and 9
10-7 ? 18 - 8 - 0
