Exploring Properties of Rational Expressions

The video tutorial introduces the concept of properties in math, focusing on the associative, commutative, and identity properties. Each property is explained with examples, demonstrating how they apply to addition and multiplication. The associative property shows how numbers can be grouped differently without changing the result. The commutative property illustrates that the order of numbers can be changed without affecting the outcome. The identity property explains how adding zero or multiplying by one keeps a number's identity unchanged.
