-3
Are you kidding me?
Well, if ou seriously didn't know this, it's -3
7-4=3
and whe you look back, you find the bigger number which is seven (which amount of money do you want more? 7 dollars? or 3 dollars?) and take the sign of the bigger number which is negative
7 + (-4) = 3
the answer is -3.
4 + 7 = 11
7 + 4 = 11
-11
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
The problem of -5 plus 7 - (-4 plus -12) is equal to 18.
16 + 2 + 9 + 4 + 7 + 8 is = 18 + 9 + 4 + 7 + 8 = 27 + 4 + 7 + 8 = 31 + 7 + 8 = 38 + 8 = 46
