Number Properties: Commutative, Associative & Distributive

1. Number Properties: Commutative, Associative & Distributive

We often find ourselves using real number properties when working on math problems. These properties come in a variety of forms, but in this lesson we'll focus on learning about the commutative, associative, and distributive properties.

The Multiplication Property of Zero: Definition & Examples

2. 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.

How to Find the Prime Factorization of a Number

3. 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.

Word Problems: Greatest Common Factor & Least Common Multiple

4. Word Problems: Greatest Common Factor & Least Common Multiple

In this video lesson, you will learn what kinds of word problems you can expect to see that involve the greatest common factor or the least common multiple. Learn what you need to do to understand these problems and then to solve them.

Mental Math: Addition and Subtraction

5. Mental Math: Addition and Subtraction

After watching this video lesson, you will get better at adding and subtracting numbers in your head without a calculator. Learn how breaking apart your addition and subtraction problems makes them easier and quicker to solve in your head.

Mental Math: Multiplication and Division

6. Mental Math: Multiplication and Division

Have you ever had to figure out the answer to a quick math problem? Sure, you can use your calculator on your phone, but what if that's out of battery life? In this lesson, we'll learn how to do mental math for multiplication and division.

Solving Mathematical Problems Using Estimation

7. Solving Mathematical Problems Using Estimation

Estimating is a method of calculating a result that is close to, but not exactly, the correct answer to a math problem. Why would you ever need to do this? This lesson reviews estimating and answers the question as to why you would do it.
