Students will review:
In this chapter, you'll learn the answer to questions including:
- How do I graph for rational numbers?
- What is the order and absolute value of real numbers?
- How do the commutative and associative properties differ?
- How do I rationalize the denominator?
- What are algebraic and transcendental numbers?
1. What are the Different Types of Numbers?
Learn all of the different types of numbers: natural numbers, whole numbers, integers, rational numbers, irrational numbers, and real numbers. This video lesson teaches you how to classify any numbers you come across.
2. Graphing Rational Numbers on a Number Line
Number lines have many uses both in mathematics and everyday life. This lesson will teach you how to graph numbers on a number line and give real-world examples of how to use number lines.
3. Notation for Rational Numbers, Fractions & Decimals
How do fractions become decimals? And how do decimals become fractions? In this lesson, we'll learn about the notation of rational numbers, fractions and decimals and learn how they're related.
4. The Order of Real Numbers: Inequalities
An inequality is an operation describing how one number can be compared to another. This lesson will describe and define inequalities and the symbols used to represent them. It will also give some examples on how to work with inequalities.
5. Finding the Absolute Value of a Real Number
You can find the absolute value of any real number. This lesson will define absolute value, explain what real numbers are and give the steps to finding the absolute value of any real number.
6. The Commutative Property: Definition and Examples
There are three major properties that deal with the addition and multiplication of numbers. One of those properties is the commutative property. This lesson will define and give examples of the commutative property and how it works.
7. The Associative Property: Definition and Examples
There are three basic number properties that help to form the backbone of algebra. One of those properties is the associative property. This lesson will define the associative property and give some examples of how it works.
8. The Multiplication Property of Zero: Definition & Examples
The number zero has different rules than other numbers; it behaves according to it's own unique properties. This lesson will define the multiplication property of zero and give some examples of how it works.
9. Algebraic Numbers and Transcendental Numbers
Math is all about numbers. In this lesson, you'll learn about the two different categories of numbers, called algebraic and transcendental. You'll learn the definition of each type and find out how common each of them is.
10. Identity Property of Addition: Definition & Example
This lesson will give you the definition of the identity property of addition. You will be shown examples to clearly illustrate the material. Following the lesson will be a brief quiz to test your knowledge.
11. Identity Property of Multiplication: Definition & Example
This lesson will give you the definition of the identity property of multiplication, examples of this property and an explanation of why this property always works. Following the lesson will be a brief quiz to test your knowledge of the material.
12. Identity Property: Definition & Examples
In this lesson, you will learn the definition of the identity property, discover the four different identity properties and examine examples that clearly illustrate these properties. Following this lesson will be a brief quiz to test your knowledge.
13. Multiplicative Identity Property: Definition & Example
In this lesson, discover what the multiplicative identity property is and view examples of the property in action. You'll also find out why this property is always true.
14. Multiplicative Inverse: Definition, Property & Examples
In this lesson, we will cover the definition of the multiplicative inverse, as well as its property. We will review some examples of the property so that we can gain a better understanding of the material. Following the lesson will be a brief quiz.
