Ch 11: CAHSEE - Matrices and Absolute Value: Tutoring Solution

About This Chapter

The Matrices and Absolute Value chapter of this CAHSEE Tutoring Solution is a flexible and affordable path to learning about matrices and absolute value. These simple and fun video lessons are each about five minutes long and they teach all of the operations involving matrices and absolute value covered on the CAHSEE math exam.

How it works:

  • Begin your CAHSEE math exam prep.
  • Identify the matrices and absolute value concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our CAHSEE Tutoring Solution will benefit any student who is trying to learn about matrices and absolute value and earn passing scores on the exam. This resource can help students including those who:

  • Struggle with understanding dilations and reflections, determinants, graphing or any other matrices and absolute value topic
  • Have limited time for studying
  • Want a cost effective way to supplement their math learning
  • Prefer learning about math visually
  • Find themselves struggling with their CAHSEE math exam preparation
  • Cope with ADD or ADHD
  • Want to get ahead in high school math

What is a Matrix?

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.

How to Take a Determinant of a Matrix

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!

What is an Absolute Value?

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!

How to Evaluate Absolute Value Expressions

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!

How to Solve an Absolute Value Equation

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!

Solving Absolute Value Practice Problems

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.

How to Graph an Absolute Value and Do Transformations

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!

Graphing Absolute Value Equations: Dilations & Reflections

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.
