Lesson: Properties of Operations over the Real Numbers Mathematics

In this lesson, we will learn how to solve problems involving operations and properties of operations on real numbers.

Lesson Plan

Students will be able to

understand and apply the following properties of addition and multiplication of real numbers:
- closure ( and ),
- commutativity ( and ),
- associativity ( and ),
- identity (or neutral) elements ( and ),
- inverse elements ( and for ),
understand that subtraction and division are neither associative nor commutative.
