1. What is a Mathematical Expression? - Definition & Examples
This lesson will explain how to recognize a mathematical expression and the parts that make up a mathematical expression. You will also learn some of the basic vocabulary used when discussing mathematical expressions.
2. Evaluating Simple Algebraic Expressions
In this lesson, we'll learn how to evaluate algebraic expressions, which involves substituting numbers for variables and following the order of operations. By the end of the lesson, you'll be an algebraic expression expert.
3. Practice Simplifying Algebraic Expressions
In this lesson, we'll practice simplifying a variety of algebraic expressions. We'll use two key concepts, combining like terms and the distributive property, to help us simplify.
4. Rewriting Algebraic Expressions Using Structure
Algebraic expressions can be written in more than one way. In this lesson, we will go through how to rewrite algebraic expressions so they look different, but are actually the same thing.
