-2 + 18 + -5 = 11
13 plus -8 = 5 ... and -18 plus -2 = -20.
5/6 + 2/18 = 15/18 + 2/18 = 17/18
9 + 2 + 30 - 5 + 18 - 19 = -1
It is: 2/9+5/18 is the same as 4/18+5/18 = 9/18 which is 1/2 simplified
18 + 2 / 4 = 18 + .5 = 18.5
2/3 + 1/9 + 5/6 = 12/18 + 2/18 + 15/18 = 29/18 = 111/18
5 + (2 x 7) - (18/5) = 15.4
5/18 + -1/6 = 5/18 - 3/18 = 2/18 = 1/9
4/9 x 2/2 = 8/18 5/18 + 8/18 = 13/18
2/18 + 5/18 = 7/18
If they are to be multiplied then the answer is 18
5 + 42 - 8 + 92 + 2 + 4 + 18 - 514 = -359
