The commutative property of multiplication states that the order in which two numbers are multiplied does not change the product. In other words, if you have a multiplication expression with two or more numbers, you can rearrange the order of the numbers and still get the same answer.
Applying the commutative property to the expression 13 × 7 × 21, we can rearrange the terms in any order we want and the product will remain the same. Here are a few examples of how we could rearrange the numbers:
1. 7 × 13 × 21 2. 7 × 21 × 13 3. 21 × 13 × 7 4. 21 × 7 × 13 5. 13 × 21 × 7
No matter how we rearrange these numbers, the product will always be the same. This is because the commutative property guarantees that multiplication is not dependent on the order of the numbers.
