Which of the following expressions demonstrates the commutative property?

The expression that demonstrates the commutative property is one that illustrates how the order of the numbers being added does not affect the sum. In this case, the expression 2 + 3 = 3 + 2 shows that switching the positions of the addends (2 and 3) results in the same total. This is the essence of the commutative property, which applies to addition (and multiplication), stating that changing the order of the numbers does not change the result.

The other options illustrate different properties of arithmetic. The first choice showcases the associative property, which focuses on how numbers are grouped rather than their order. The third choice demonstrates the identity property, which states that adding zero to any number does not change its value. The fourth option also illustrates the associative property by showing that the grouping of the numbers can be rearranged without altering the sum.

This understanding of the commutative property is essential for students as it lays a foundational concept in arithmetic, enabling them to manipulate and simplify expressions confidently.
