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.

Using Parentheses in Math: Rules & Examples

2. Using Parentheses in Math: Rules & Examples

In this lesson, we will explore how to use parentheses to clarify numbers, indicate multiplication, and group numbers together for the order of operations. After exploring the rules of parentheses, review your understanding of this lesson with a short quiz.

How to Determine When a Numerical Expression is Undefined

3. How to Determine When a Numerical Expression is Undefined

We get all kinds of problems in math. We sometimes get numerical expressions that are undefined. Watch this video lesson to learn what it means to be undefined and how to find when a numerical expression is undefined.

Remainder in Math: Definition & Example

4. Remainder in Math: Definition & Example

Division problems often result in remainders. In this lesson, we will define the remainder and use long division of numbers and synthetic division of polynomials to compute remainders.

What are Factors & Multiples?

5. What are Factors & Multiples?

A mathematician needs to know how to work with numbers. In this lesson, you'll learn two ways to work with numbers: using factors and multiples. You'll also learn the definitions of factors and multiples and how to find the factors and multiples of a number.

What Are Prime Numbers? - Definition & Examples

6. What Are Prime Numbers? - Definition & Examples

Learn the definition of prime numbers and composite numbers while working through a few examples of how to identify them. Then expand your knowledge by learning three rules that help you determine whether or not a number is prime.

What Are Composite Numbers? - Definition & Examples

7. What Are Composite Numbers? - Definition & Examples

In this lesson, you'll learn what composite numbers are and briefly touch on prime numbers. You'll also learn a couple of rules about composite numbers. Then, you can test your new knowledge with a brief quiz.
