TASC Math: Real Numbers - Chapter Summary
The lessons in this chapter can help you refresh your knowledge of real numbers as you prepare for the TASC Mathematics test. As you progress through the chapter, you'll review the different types of numbers, number notation, absolute value and much more. When you're finished with the chapter, you should be able to:
- Compare the different types of numbers
- Recognize the properties of rational/irrational numbers
- Graph rational numbers on a number line
- Use fraction, decimal and rational number notation
- Understand the order of real numbers
- Find the absolute value of real numbers
The video lessons in this chapter are taught by experienced instructors, and they include fun illustrations and examples. Each lesson has a multiple-choice quiz and a transcript that highlights key terms. A chapter exam is also available to help test your knowledge of real numbers. You can access these study resources online at any time that fits your schedule, and you can submit questions to our math experts if you need any extra help with the material.
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. Properties of Rational & Irrational Numbers
In this video, we'll explore rational and irrational numbers by looking at what happens when they're added and multiplied. We'll use examples to explain these properties and learn more about rational and irrational numbers.
3. 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.
4. 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.
5. 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.
6. 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.
