It is: 12+7+2 = 21
2 + 12 + 7 = 21
-12
6 + 13 + 2 + 12 + 7 + 14 = 54
12 * (243 + 2) - 7 = 2933
yes. think of 6/12 plus 1/12. that is 7/12!
It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
83
7/12 + 1/6 = 7/12 +(1×2)/(6×2) = 7/12 + 2/12 = (7+2)/12 = 9/12
-2
12 + 7 - 2 12 + 7 = 19 19 - 2 = 17 or 7 - 2 = 5 5 + 12 = 17
24/-2 + 7 = -12 + 7 = -5
