You can break down this equation to make it easier.
9+8= 17
7+6=13
17+13= 30
Thus, the answer is 30.
4 + 5 + 6 + 7 + 8 + 9 = 39
9 + 8 + 7 + 6 + 5 + 4 = 39
9 + 6 + 9 + 6 + 9 + 8 + 5 + 2 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 99
2 + 4 + 8 + 6 + 3 + 7 + 9 + 8 = 47
9 + 8 + 7 + 6 + 5 + 4 + 3 = 42
6 plus 7
2 + 5 is 7 + 6 =13 + 7 = 20 + 8 = 28 + 9 = 37 + 10 is 47.
It is 8/9 plus 6/7 = 1.'746031' recurring '746031'
8+5 = 6+7 = 8+9 13 = 13 = 17 Can you rephrase? the question isn't too clear...
1+2+3+4+5+6+7+8+9=37
1+2+3+4+5+6+7+8+9= 45 :)
8 plus 7 divided by 5 then add 6.
