Properties of Multiplication

The video tutorial covers key multiplication properties: commutative, associative, distributive, identity, and zero. It explains how these properties work with examples, emphasizing the flexibility and strategies they offer in solving multiplication problems. The distributive property is highlighted with a detailed breakdown, while identity and zero properties are briefly discussed. The tutorial concludes with a recap of all properties.

What does the commutative property of multiplication state?

• Multiplying by zero gives zero.

• Factors can be grouped in any way without changing the product.

• The order of factors can be changed without affecting the product.

• Multiplying by one leaves the factor unchanged.
