Which property states that order of the addends does not affect the sum?

a. commutative property of addition

b. associative property of addition

c. reflexive property of addition

d. additive identity property

Option A

Commutative property of addition  states that order of the addends does not affect the sum

Solution:

The commutative property of addition tells us that it does not matter which number we add first , We will still get the same answer if we add them backwards

This property is represented as:

For two numbers a, b:

a + b = b + a

In case of three numbers a, b, c:

a + b + c = c + b + a = b + a + c

So no matter how the addends are placed, the result of the operation (sum) remains the same

For example:

When we are adding 4 and 5

4 + 5 = 9 or 5 + 4 = 9 both the ways the result remains same

Thus Commutative Property of Addition states that changing the order of addends does not change the sum

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
