The additive property.
Equality
do you mean what is 3+6+9-12? The answer is 6: 3+6=9 9+9=18 18-12=6 :)
it is 18+(-3)-6=18-3-6=18-9=9.thus the answer is 9
6 greater than 18 plus 9 = 6 greater than 27 = 33
4x+6-7x+9=18-3x+15=18-3x=3x=-1
1/9 = 2/18 3/6 = 9/18 2/18 + 9/18 = 11/18
27-9 =18. 18/3 =6
5/6 plus 7/9 is 1 and 11/18.
2/3 + 1/9 + 5/6 = 12/18 + 2/18 + 15/18 = 29/18 = 111/18
-2/9 + 5/6 = -4/18 + 15/18 = 11/18
1/9 + 5/6 = 6/54 + 45/54 = 51/54 = 17/18 <-------------------------
1/18 + 1/6 is 2/9
