the answer to -7 + 4 is -3
what u do is u turn the Addition sign to a subtraction and then the problem is
-7-4 and on a number line if u go to -7 then go back 4 times u will get to -3
over all ur answer is -3
7 + (-4) = 7 - 4 = 3
3 + 4 + 7 = 14
16 + 2 + 9 + 4 + 7 + 8 is = 18 + 9 + 4 + 7 + 8 = 27 + 4 + 7 + 8 = 31 + 7 + 8 = 38 + 8 = 46
SUM means plus 4+7=11
4-7+10=7
9 + 8 + 7 + 6 + 5 + 4 = 39
7 + 5 + 4 + 5 + 3 + 4 + 6 + 5 + 4 + 5 + 6 + 4 + 7 = 65
16?
-7
-5+7--4+12 = 18
102
-4 + 5 + (-7) = -6
3 + 4 + 7 = 14
9 + 4 + 7 + 8 = 28
Commutative property of addition. :)
The commutative property
16 + 2 + 9 + 4 + 7 + 8 is = 18 + 9 + 4 + 7 + 8 = 27 + 4 + 7 + 8 = 31 + 7 + 8 = 38 + 8 = 46
The problem of -5 plus 7 - (-4 plus -12) is equal to 18.
