# Commutative vs. Associative: What's the Difference?

Edited by Sara Rehman || By Sawaira Riaz || Published on January 6, 2024

**Commutative property refers to the ability to change the order of numbers without affecting the result, while associative property involves changing the grouping of numbers without changing the outcome.**

## Key Differences

The commutative property, applicable in operations like addition and multiplication, states that the order of numbers does not affect the end result. For example, in addition, 3 + 5 is the same as 5 + 3. The associative property, on the other hand, deals with the grouping of numbers. It asserts that how numbers are grouped in an operation (addition or multiplication) does not change the sum or product. An example is (2 + 3) + 4 equals 2 + (3 + 4).

Commutative property simplifies calculations by allowing flexibility in the order of operations. This property is not applicable in subtraction and division. Associative property is helpful in making complex calculations easier by altering the grouping of numbers, especially in longer expressions. Like commutativity, it also does not apply to subtraction and division.

In the commutative property, the focus is on the sequence of the numbers or elements involved in the operation. This property is particularly useful in mental math and algorithmic calculations. The associative property emphasizes the way elements are associated or grouped together, which is crucial in algebraic expressions and solving equations.

The commutative property is represented by the equation a + b = b + a or a × b = b × a, showcasing the interchangeability of numbers. The associative property is symbolized by (a + b) + c = a + (b + c) or (a × b) × c = a × (b × c), indicating the same result despite different groupings.
