The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be the same. The correct option is B.
What is the associative property of addition?
Suppose you've got 3 numbers a, b, and c.
Then, we have
(a+b) + c = a + (b + c)
This property is called associative property and it is called so because we can associate b with a, or b with c without altering the value of the addition.
What is the commutative property of addition?
The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be the same.
For two numbers x and y, we have:
x + y = y + x
Thus, if we take 3 numbers as a,b and c, then:
a + b + c = b + a + c = b + c + a = a + c + b = c + a + b = c + b + a
And so on for any amount of numbers.
The best use of the associative and commutative properties to make simplifying -1/3-10+7+2/3+5 easier is [-1/3+(-10)]+[7+2/3+5].
Hence, the correct option is B.
