Understanding the Commutative Law of Multiplication

The video tutorial explains the commutative law of multiplication, which states that the order of factors does not affect the product. It demonstrates this concept using the example of 2 times 34 and 34 times 2, showing that both yield the same result, 68. The tutorial emphasizes that the commutative property allows flexibility in the order of multiplication, making calculations easier.

What does the commutative law of multiplication state?

• Division is the opposite of multiplication.

• Multiplication is always greater than addition.

• The order of multiplication does not matter.

• The order of addition matters.
