### About This Chapter

## Ohio EOCE Integrated Math I: Matrices & Absolute Value - Chapter Summary

The lessons that you can find in this chapter will be helpful in teaching you about topics related to matrices and absolute value in mathematics. Make sure to go through each lesson if you are preparing to take the Ohio EOCE Integrated Math I exam. When reviewing the lessons, you will learn about topics such as:

- The definition of a matrix
- Taking the determinant of a matrix
- Absolute value
- Evaluating, solving, and graphing absolute value expressions
- Dilations and reflections in graphing absolute values

Each lesson is taught by an instructor with specific expertise in these areas, so all of the information you learn will be accurate and comprehensive. Make sure after you finish the lessons to test your knowledge of some of these topics by taking the chapter's practice quizzes.

### 1. What is a Matrix?

As math gets more and more complicated and there become more and more numbers flying around, it becomes really handy to put all these numbers in a nice organized grid... hello matrices! Learn about what they are and why there are used.

### 2. How to Take a Determinant of a Matrix

Matrices are incredibly powerful and can help you do all sorts of things, but one of the most basic (and surprisingly helpful) operations you can perform on one is to take its determinant. Learn how to do that here!

### 3. What is an Absolute Value?

When we're talking and comparing numbers, we often don't care whether its positive or negative, just how big it is. This is often called the magnitude of a number and we find it by taking the absolute value. Learn all about it here!

### 4. How to Evaluate Absolute Value Expressions

Substituting values into absolute values doesn't have to be too hard, but it can be if you're given deceiving beginning information. See if you're up to it by checking out this video!

### 5. How to Solve an Absolute Value Equation

Once you get familiar with any new operation, the next step in any algebra class is to learn how to solve equations with that operation in them. Absolute values are no different. Solve absolute value equations here!

### 6. Solving Absolute Value Practice Problems

There are many easy mistakes to make when solving absolute value equations. Learn how to avoid those mistakes here by working on examples of absolute value equations with operations on the inside and the outside of the absolute value.

### 7. How to Graph an Absolute Value and Do Transformations

Absolute value graphs normally look like the letter 'V', but transformations can change that 'V' in a number of different ways. As well as teaching you how to graph absolute values, this video will focus on a specific group of transformations called translations. Learn all about what that means here!

### 8. Graphing Absolute Value Equations: Dilations & Reflections

Although a basic absolute value graph isn't complicated, transformations can make them sufficiently confusing! In this lesson, you'll practice different transformations of absolute value graphs.
