Expanding Expressions: Rewriting and Equivalence

The video tutorial teaches how to rewrite expressions by expanding them. It begins with an introduction to the concept, followed by a review of basic multiplication and the commutative property. The tutorial then provides examples, including a scenario involving a square pool, to demonstrate how expressions can be expanded. The video concludes with an additional example, reinforcing the concept that expressions can be rewritten in different forms using the commutative property.

What does it mean to expand an expression, and how is it demonstrated in the lesson?
