It is not possible to answer the question since there is no visible operator between 9 and 8.
It is: -9+8+(-5)+3+1 = -2
9 + 6 + 9 + 6 + 9 + 8 + 5 + 2 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 99
9 + 8 + 7 + 6 + 5 + 4 + 3 = 42
89
1/3 + 5/9 3/9 + 5/9 8/9
3/6 + 9/8 = 13/8 or 1 and 5/8
9 divided 3 is 3 3 plus 5 is 8 8 times 3 is 24
1+2+3+4+5+6+7+8+9=37
1 + 6 + 9 - 8 + 4 - 5 + 2 + 3 = -6
1+2+3+4+5+6+7+8+9= 45 :)
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55
1 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 46
