### About This Chapter

## TExES Mathematics 4-8: Basic Arithmetic - Chapter Summary

The fundamentals of mathematics, number systems and the base-ten system, are the starting point of the videos and lessons in this study guide. Here, you will complete lessons and assessments created by our instructors to give you practice in the sort of material on which you will be tested when you take the TExES Mathematics 4-8 exam as part of your Texas educator licensure process. After completing this chapter, you should be able to do the following:

- Identify the purpose of the number line
- Use mathematical models to solve problems
- Perform basic operations including addition, subtraction, multiplication, and division
- Multiply and divide large numbers

The videos included in this chapter are fun and brief, usually under 10 minutes. Take the quiz at the end of the lessons as well as the end-of-chapter exam to measure your test readiness and practice your test-taking skills. You have the option of watching the lessons in any order you wish, and you can even skip to specific portions of the videos using the handy tags.

### 1. Number Systems and The Base-Ten System

Ever think that a computer doesn't get what you want it to do? Don't be surprised; it is living in a world where it can only count to 1. This lesson explains number systems, including our base-ten system and a computer's base-two system.

### 2. 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.

### 3. Using Mathematical Models to Solve Problems

Mathematical modeling simply refers to the creation of mathematical formulas to represent a real world problem in mathematical terms. This lesson reviews the creation and pitfalls of mathematical models.

### 4. 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.

### 5. 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.

### 6. 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.

### 7. 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.

### 8. 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.

### 9. 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.
