Commutative property of addition. :)
The commutative property
2 + 3 - 4 + 7 = -6
7 + 5 + 4 ÷ 2 + 7 = 21
The answer to the math problem 2 plus 4 minus 7 plus 123 is 122.
7 + 21 + 2 + 86 + 4 = 120
7
16 + 2 + 9 + 4 + 7 + 8 is = 18 + 9 + 4 + 7 + 8 = 27 + 4 + 7 + 8 = 31 + 7 + 8 = 38 + 8 = 46
1+2+4 = 7
If: x + 2/2 + x + 5/7 = 4 Then: x = 8/7
102
depends on how question is wordedif (3 + 7) times (2 + 4)then 10 x 6 = 60also could be3 plus (7 x 2) plus 4 = 21or could be[(3 + 7) x 2] + 4 = 24
