## Learning Objectives

- Review the basic types of numbers.
- Practice arithmetic calculations with signed and whole numbers.
- Provide a definition for the order of operations.
- Calculate the greatest common factor or least common multiple.
- Understand the prime factorization of a number.

### 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. Arithmetic with Whole Numbers

There are four basic mathematical operations: addition, subtraction, multiplication, and division. These four operations are used in a wide range of everyday skills and are the fundamental blocks of arithmetic.

### 3. 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.

### 4. What Is The Order of Operations in Math? - Definition & Examples

The order of operations is the steps used to simplify any mathematical expression. In this video, learn how to solve problems using these steps and easy tricks to remember them.

### 5. How to Find the Prime Factorization of a Number

The prime factorization of a number involves breaking that number down to its smallest parts. This lesson will show you two different ways to discover the prime factorization of any number.

### 6. 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!

### 7. 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!

### 8. Dividend: Definition & Overview

In mathematics, the dividend is the amount of something you want to divide into smaller parts. In this lesson, we will learn more about the dividend and how it works, then try some example problems.

### 9. Mixed Numbers: How to Add, Subtract, Multiply & Divide

In this lesson, we will learn how to calculate with fractions, a topic many students struggle with. Although considered elementary, fractions are found at all levels of mathematics, and knowing how to work with them is an important skill.
