Repeating Decimals: Definition & Examples

1. Repeating Decimals: Definition & Examples

Repeating decimals are a special type of number. In this lesson, we will explore the definition of this number and look at some of the properties it holds.

Changing Between Decimals and Fractions

2. Changing Between Decimals and Fractions

In this video lesson, you will learn about the usefulness of knowing how to change quickly between decimals and fractions. You will also learn how changing from a decimal to a fraction is different than changing from a fraction to a decimal.

Scientific Notation: Definition and Examples

3. 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.

Comparing Numbers Written in Scientific Notation

4. Comparing Numbers Written in Scientific Notation

After watching this video lesson, you will be able to compare numbers written in scientific notation with each other. You will learn how to tell which is larger and which is smaller.

How to Multiply & Divide in Scientific Notation

5. How to Multiply & Divide in Scientific Notation

Scientists, engineers, and other people who work with really big or really small numbers often choose to express those numbers in scientific notation. In this lesson, we'll learn how to multiply and divide in scientific notation.

Using Scientific Notation to Approximate

6. Using Scientific Notation to Approximate

When you have really large numbers or really small numbers, the exact number is not always that important. In this lesson, you'll learn how scientific notation allows you to approximate these numbers and make them easier to use.

Using Scientific Notation on a Scientific Calculator

7. Using Scientific Notation on a Scientific Calculator

This lesson will give you a brief review of scientific notation. We will then look at how to use scientific notation on a scientific calculator. This lesson will include examples and the keystrokes involved with the scientific calculator.

Using Scientific Notation in Ideal Gas Law Problems

8. Using Scientific Notation in Ideal Gas Law Problems

The ideal gas law relates pressure, volume, molar amount of gas and temperature. In this lesson, we will learn how to use the ideal gas law when values are very large or very small. We will be using scientific notation in our calculations.
