What does the commutative property state about addition?

The correct answer highlights that the order in which numbers are added does not change the result of the addition. This characteristic is central to the commutative property, which applies specifically to addition (as well as multiplication). For example, if you have the numbers 2 and 3, adding them in any order yields the same sum: 2 + 3 equals 5, and 3 + 2 also equals 5. This property allows for flexibility in calculations, making arithmetic operations more manageable.

The other options provided do not accurately represent this fundamental concept. For instance, stating that the order of addition affects the sum contradicts the definition of the commutative property. Similarly, claiming that addition is not commutative is incorrect because one of the foundational rules of arithmetic is that addition is indeed commutative. The statement suggesting the sum is always negative presents a misconception, as sums can be positive, negative, or zero depending on the numbers involved. Thus, the correct understanding of the commutative property provides clarity and consistency in mathematics, particularly in addition.
