11
The Answer is Commutative Property
-18
-18
they are already even! 7 and 11 are the same as 7 plus 11. 7 plus 11 is 18! 18 is even!
-5+7--4+12 = 18
If that was 7 x 210 + 18, the answer is 1,488. If it was 7,210 + 18, then the answer is 7,228.
7-18 plus 4(3-12) divided by 9
18(7) + 5 = 131
-18 + 25 = 7
60.
The problem of -5 plus 7 - (-4 plus -12) is equal to 18.
25 + 18 = 43
