Ch 1: Basic Arithmetic

About This Chapter

Use this chapter to review basic arithmetic and prepare for the mathematical reasoning portion of the GED exam. Video lessons and quizzes explain such topics as associative properties, least common multiples and binary operations in a way that's clear and easy to follow.

Basic Arithmetic - Chapter Summary

Practice solving math problems that include positive integers, negative integers and zeros with the lessons included in this basic arithmetic chapter. Instructors discuss the following topics to prepare you for mathematical reasoning questions on the GED exam:

  • Binary and non-binary operations
  • Commutative and associative properties
  • Whole number addition and subtraction
  • Whole number multiplication and division
  • Greatest common factors and least common multiples
  • Graph quadrants, axis, ordered pairs and intercepts

Whether you need to learn the basic principles behind solving mathematical equations or would like additional practice problems to affirm your mastery of these topics, we've got you covered. Brief video lessons are taught by experienced educators whose instructional styles make the material easy to follow. There are also lesson transcripts and corresponding self-assessment quizzes that allow you to try your hand at solving equations similar to the sample problems included in many of the lessons.

Basic Arithmetic - Chapter Objectives

The GED exam is a standardized test used to grant high school equivalency diplomas to adult learners who have demonstrated that they have the academic skills needed to succeed on the job or in a postsecondary education program. The test consists of four sections, including a mathematical reasoning portion assessing your quantitative and algebraic problem-solving skills. It's in this 90-minute section where you'll benefit from a knowledge of basic arithmetic functions as well as the ability to reorder operations, determine the least common multiple and read a graph - all of which are covered in this chapter's video lessons and transcripts.

What Is a Number Line?

1. What Is a Number Line?

A number line is a visual representation of all real numbers. In this lesson, we'll learn how to identify points on a number line. We'll also practice addition and subtraction, letting the number line do all the hard work.

Binary and Non-Binary Operations

2. Binary and Non-Binary Operations

Binary and non-binary are two terms that might really scare you, much like an operation may scare you. But don't worry, this lesson is super fun and super easy. You'll learn the definitions of these terms and see examples of each.

How to Perform Addition: Steps & Examples

3. How to Perform Addition: Steps & Examples

Addition is one of the basic operations of math. You can say that the whole of mathematics is based on addition. Without addition, we wouldn't have higher math. Watch this video to learn how to add.

How to Perform Subtraction: Steps & Examples

4. How to Perform Subtraction: Steps & Examples

Subtraction is one of the basic operations in math. Watch this video lesson to learn how you can view and understand subtraction so that you can easily perform it.

How to Perform Multiplication: Steps & Examples

5. How to Perform Multiplication: Steps & Examples

Multiplication, one of the basic operations of math, is important not just in elementary math but also in higher math. Watch this video lesson to learn how you can multiply with ease.

How to Multiply Large Numbers: Steps and Examples

6. How to Multiply Large Numbers: Steps and Examples

After watching this video lesson you will be able to multiply any two numbers together. You will learn how to use your knowledge of multiplying smaller numbers together to multiply larger numbers with ease.

How to Perform Division: Steps & Examples

7. How to Perform Division: Steps & Examples

Watch this video lesson to learn how you can divide. Division is one of the basic operations of math. It is one of the fundamental operations that all higher mathematics depends upon.

Performing Long Division with Large Numbers: Steps and Examples

8. Performing Long Division with Large Numbers: Steps and Examples

After watching this video lesson, you will be able to divide larger numbers. You'll learn an easy to follow procedure that you can use to divide any two numbers.

Arithmetic Calculations with Signed Numbers

9. Arithmetic Calculations with Signed Numbers

Signed numbers are often referred to as integers. Integers include both positive and negative numbers. In this lesson, you will learn how to add, subtract, multiply, and divide integers.

The Commutative Property: Definition and Examples

10. 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.

The Associative Property: Definition and Examples

11. 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.

The Multiplication Property of Zero: Definition & Examples

12. 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.

How to Find the Greatest Common Factor

13. How to Find the Greatest Common Factor

If the factors of a number are the different numbers that you can multiply together to get that original number, then the greatest common factor of two numbers is just the biggest one that both have in common. See some examples of what I'm talking about here!

How to Find the Least Common Multiple

14. How to Find the Least Common Multiple

The least common multiple of two numbers is the smallest number that can be divided evenly by your two original numbers. See some examples of what I'm talking about here!

What Are the Different Parts of a Graph?

15. What Are the Different Parts of a Graph?

Being able to read a graph isn't just vital for an algebra class. Graphs and charts are used everywhere! We'll take a crash course on the basic x/y plane used in algebra and the fundamental vocab you need.
