The answer is 29. 18 + 11 _______ 29
-18
9 plus 11 (20) plus 15 (35) plus 18 is equal to 53
-18
-2 + 18 + -5 = 11
they are already even! 7 and 11 are the same as 7 plus 11. 7 plus 11 is 18! 18 is even!
11
17 + 14 + 17 + 19 + 18 + 13 + 11 = 109
-29
It is -4-11+18 = 3 Think of it as 18 -11 =7 and 7-4 =3
112
-11=18+s/5
8/18 plus 1/6 = 11/18
