## TExES Math 4-8: Number Theories & Computation Strategies - Chapter Summary

These lessons can help you review number properties and computations. The videos and text transcripts address topics that may be covered on the TExES Math 4-8 exam, including the commutative property, finding the prime factorization of a number and the multiplication property of zero. After finishing this chapter, you should be prepared to do the following:

- Define the commutative property
- Give examples of the associative property
- Explain what the multiplication property of zero is
- Use the distributive property
- Find the prime factorization of a number
- Identify the greatest common factor and least common multiple

Let our qualified instructors guide you through each topic in preparation for the test. Jump to specific video sections using the timeline feature and use the text transcripts to review the concepts you need the most help with.

### 1. The Commutative Property: Definition and Examples

There are three major properties that deal with the addition and multiplication of numbers. One of those properties is the commutative property. This lesson will define and give examples of the commutative property and how it works.

### 2. The Associative Property: Definition and Examples

There are three basic number properties that help to form the backbone of algebra. One of those properties is the associative property. This lesson will define the associative property and give some examples of how it works.

### 3. The Multiplication Property of Zero: Definition & Examples

The number zero has different rules than other numbers; it behaves according to it's own unique properties. This lesson will define the multiplication property of zero and give some examples of how it works.

### 4. Distributive Property: Definition, Use & Examples

After completing this lesson, you will be able to state the distributive property and apply it to various types of problems. You will also be able to accurately perform the mathematical operations that are involved with the distributive property.

### 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!
