MTEL Middle School Mathematics: Exponents - Chapter Summary

Bring back to mind those early lessons about mathematical logic and number sense as you check out these videos to go over the rules and properties of exponents. If you want to do well on the MTEL Middle School Mathematics test, you will need to make sure you comprehend the following topics that are covered in these lessons:

  • The five key properties of exponents
  • Definitions for negative and zero exponents
  • Steps for simplifying equations with exponents
  • Characteristics of rational exponents
  • Techniques for simplifying rational exponent expressions
  • Converting negative exponents into fractions
  • Scientific notation and practice equations

Sometimes the best way to study for the MTEL Middle School Mathematics test is to first assess what you currently know. Our site offers two useful assessment tools, including quizzes for every lesson and exams for entire chapters. Answer the multiple-choice questions and determine how much information you already understand. As you identify the areas in which you are less familiar, take the time to watch the video lessons and read through the transcripts.

Exponent: Definition & Properties

1. Exponent: Definition & Properties

An exponent tells you how many times to use a number in a multiplication problem. This lesson will define the properties of exponents and how to interpret them. There will also be a quiz at the end of the lesson.

What Are the Five Main Exponent Properties?

2. What Are the Five Main Exponent Properties?

We'll look at the five important exponent properties and an example of each. You can think of them as the order of operations for exponents. Learn how to handle math problems with exponents here!

How to Define a Zero and Negative Exponent

3. How to Define a Zero and Negative Exponent

The zero and negative exponent properties are two you will use quite a lot in mathematics. The negative exponent property can be confusing, but when you remember a couple fun ideas, you will get it right every time!

How to Simplify Expressions with Exponents

4. How to Simplify Expressions with Exponents

In this video, we will put all of the exponent properties we have learned together. Don't let lots of numbers and letters confuse you! Simplifying exponents can be easy and fun!

Rational Exponents

5. Rational Exponents

In this video, learn how to go from a rational exponent to a radical expression and back. No tricks or magic, just good math! We'll review the basics and look at a few examples.

Simplifying Expressions with Rational Exponents

6. Simplifying Expressions with Rational Exponents

Simplifying expressions with rational exponents is so easy. In fact, you already know how to do it! We simply use the exponent properties but with fractions as the exponent!

Changing Negative Exponents to Fractions

7. Changing Negative Exponents to Fractions

A negative exponent isn't like a normal exponent. In this lesson, we'll learn about negative exponents and how they lead us to fractions. We'll practice with numbers and variables.

Scientific Notation: Definition and Examples

8. Scientific Notation: Definition and Examples

Scientific notation is a special way of writing numbers so they are easier to work with. This lesson will define scientific notations and show some examples of how to convert numbers from standard notation to scientific notation and back.

Scientific Notation: Practice Problems

9. Scientific Notation: Practice Problems

Scientific notation has a lot of exponents, but it's really not that bad - and it's really convenient for working with awkwardly big or small numbers! Get some practice here.
