Set Notation: Definition & Examples

1. Set Notation: Definition & Examples

After completing this lesson, you will know how to write a set using words and using mathematical symbols. You will also know how to define sets and how to interpret sets that are displayed in set notation.

Subsets in Math: Definition & Examples

2. Subsets in Math: Definition & Examples

After completing this lesson, you should be able to define the concept of subsets in math. You should also be ready to write subsets using proper set notation. Finally, you should be able to identify sets that are subsets of other sets.

What are Irrational Numbers? - Definition & Examples

3. What are Irrational Numbers? - Definition & Examples

Irrational numbers may not be crazy, but they do sometimes bend our minds a little. Learn about common irrational numbers, like the square root of 2 and pi, as well as a few others that businessmen, artists, and scientists find useful.

Converting from Percent Notation to Decimal Notation

4. Converting from Percent Notation to Decimal Notation

Knowing how to convert a percent to a decimal can be a useful skill in many different situations. This lesson will show you how to perform that conversion and places where this skill will be helpful.

Converting Numbers to Scientific Notation

5. Converting Numbers to Scientific Notation

After watching this video lesson, you will be able to convert any number you come across into scientific notation. You will also learn why scientific notation is used and where you are most likely to see it.

Expanded Notation for Decimals

6. Expanded Notation for Decimals

Using expanded notation to express numbers in standard form can be a helpful way to decompose a number into its component parts for ease of use in mental math and other applications. In this lesson, learn how to write numbers in expanded notation form.

The Order of Real Numbers: Inequalities

7. The Order of Real Numbers: Inequalities

An inequality is an operation describing how one number can be compared to another. This lesson will describe and define inequalities and the symbols used to represent them. It will also give some examples on how to work with inequalities.
