Students will review:
This chapter helps students review the concepts in an algebraic expressions unit of a standard math course. Topics covered include:
- Expressing relationships algebraically
- Evaluating simple algebraic expressions
- Combining like terms in algebraic expressions
- Simplifying algebraic expressions
- Applying the commutative and associative properties
- Applying the distributive property
1. What is a Variable in Algebra?
Did you ever encounter something like a + b = c and wonder how all these letters snuck into a math problem? In this lesson, we'll learn about variables, as well as other parts of equations, constants and coefficients.
2. Expressing Relationships as Algebraic Expressions
What do you do when you don't know what a number is but you do know how it relates to something else? You use an algebraic expression. In this lesson, we'll learn how to express relationships as algebraic expressions.
3. 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.
4. The Commutative and Associative Properties and Algebraic Expressions
The order of operations is important and useful, but a few mathematical properties highlight cases where order doesn't matter. In this lesson, we'll learn about the commutative and associative properties, which may save you time and effort.
5. The Distributive Property and Algebraic Expressions
The order of operations is great. But sometimes we need to bend the rules to simplify an equation. Fortunately, the distributive property gives us a scenario in which this is okay. Learn all about it in this lesson.
6. Combining Like Terms in Algebraic Expressions
When you have an algebraic expression that's much too long, it would be great if you could simplify it. That's when knowing how to combine like terms comes in. In this lesson, we'll learn the process of combining like terms and practice simplifying expressions.
7. 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.
8. Negative Signs and Simplifying Algebraic Expressions
Don't let negative signs get you down. In this lesson, we'll stay positive as we practice simplifying algebraic expressions that have those tricky negative signs.
9. Algebraic Model: Definition & Examples
Algebraic models are used frequently in mathematics. This lesson will offer a definition of algebraic models and use multiple examples to familiarize you with the concept. We'll learn what algebraic models are, how to create them, and how to use them.
10. Modulus in Math: Definition & Examples
A modulus in mathematics has to do with modular arithmetic, also called clock arithmetic. In this lesson, we'll explore the concept of a modulus. Through definition and example, we'll become familiar with what a modulus is and how to work with it.
11. Simplifying Radical Expressions with Variables
What do you think of when you hear the word 'radical'? You may think of something that is extreme or even a person that is a political activist. In this lesson, you will learn what a radical is in math and how to simplify radical expressions.
