I'm assuming the missing Arithmetic operators in the question, is as shown in my answer?
(7 × 8) + (5 × 6) = 86
4 + 5 + 6 + 7 + 8 + 9 = 39
9 + 8 + 7 + 6 + 5 + 4 = 39
9 + 8 + 7 + 6 + 5 + 4 + 3 = 42
8 plus 7 divided by 5 then add 6.
9 + 6 + 9 + 6 + 9 + 8 + 5 + 2 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 99
2 + 5 is 7 + 6 =13 + 7 = 20 + 8 = 28 + 9 = 37 + 10 is 47.
53
If you put the numbers in order it is: 0, 0, 1, 2, 4, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 6, 6, 7, 7, 7, 7, 8, 9. Since there are 25 numbers, we are looking for the thirteenth number, which is 5.
The answer is 39.7 + 8 = 15 + 4 = 19 + 7 = 26 + 5 = 31+ 6 = 37 + 2 =39
-2b+8-4b = -5-11b+7 -2b-4b+11b = -5+7-8 5b = -6 b = -6/5
positive 5
8+5 = 6+7 = 8+9 13 = 13 = 17 Can you rephrase? the question isn't too clear...
