The commutative property establishes that changing the order of addends or factors does not change the sum or product: and for whole numbers. It supports efficient mental calculation and recognizing equivalent expressions, while distinguishing operations for which the property does not hold, such as subtraction and division; this scope does not extend to more abstract algebraic structures.
The commutative property means you can change the order of numbers in addition or multiplication without changing the answer.
Example: Find .
So,
Changing the order can make a problem easier to solve mentally. Remember, this property works for addition and multiplication, but not generally for subtraction or division.
