Writing to explain if you know that 4 x 5 = 20, how can you use the Commutative (Order) Property to find 5 x 4?

To use the Commutative Property to find the product of 5 x 4 if you already know that 4 x 5 = 20, you need to understand that the Commutative Property states that the order of the numbers does not affect the result when performing multiplication.

In other words, it means that if you switch the order of the factors, the product will remain the same. In mathematical terms, for any two numbers a and b, a x b = b x a.

Applying this property to the equation you provided, where 4 x 5 = 20, you can conclude that 5 x 4 would also equal 20. That's because swapping the order of the factors simply rearranges the factors, but the product remains the same.

Therefore, you can confidently say that 5 x 4 = 20 using the Commutative Property.
