17 + 13 + 12 + 12 + 6 + 9 = 69.
-13+4+(-8)= -9+(-8) = -9-8 = -17
13
The answer is 270. Simply add up all of the numbers arithmetically like you would for two plus two. To make sure the answer is correct, check your work using a calculator.
17 plus 15 plus 13 equals 45.
6 - (-9) = 15 15 + 2 = 17 17 - 4 = 13 is the answer.
17 + 14 + 17 + 19 + 18 + 13 + 11 = 109
8+5 = 6+7 = 8+9 13 = 13 = 17 Can you rephrase? the question isn't too clear...
13. (9+17)/2=13
17 + 9 = 26
false
14 + 13 + 9 = 36
