State the commutative property of multipication, and provide an example using two different numbers

Answers

Step-by-step explanation: The commutative property of multiplication states that changing the order of the factors does not change the product.

Example:

4 × 10 ≈ 10 × 4

If we multiply both these numbers together, we will get the same answer which is 40. This means that 4 × 10 must be equal to 10 × 4.

Example:

3 × 2 ≈ 2 × 3

Both of the answers will equal 6 which means that they are equal to each other.

The commutative property of multiplication (or any other forms of math) states that two or more numbers can be multiplied (*or any other forms of math) in any order.

Example: 4x3x9=108

Just like: 4x9x3=108

Or: 9x3x4=108

Another example: 10x5x2=100

Just like: 5x2x10=100

Or: 2x10x5=100
