It is the commutative property as well as the associative property. Without the second, the equality need not hold.
The Commutative Property of Addition.
16 + 31 = 31 + 16This shows COMMUTATIVE PROPERTY OF ADDITION. It means that changing the order of the addends does not affect the sum.
It is the property that equals plus equals are equals.
16 plus 10 plus 8 plus 6 plus 2 is equal to 42.
10 + 16*10 = 10+160 = 170
-16+(-10) = -26
the answer is 16, bcuz 5+5=10, and then 10+6 equalls 16.
-16
-16
2 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 = 106
If you mean: 4--16 = 4+16 which is correct because --16 = +16
16 + 2x = 10 + 8x 2x - 8x = 10 - 16 -6x = -6 x = 1 Check: 16 + 2(1) = 10 + 8(1) 18 = 18
