In this video lesson, you will learn how to identify both prime and composite numbers. You will also learn what makes the numbers unique, as well as the characteristics of both these types of numbers.

Changing Between Decimals and Percents

3. Changing Between Decimals and Percents

Watch as we go on a rollercoaster ride in changing from a decimal to percent and then back again. Learn to master this technique so you can get as fast as a rollercoaster going downhill on tests and quizzes when you have to convert between the two.

Changing Between Decimals and Fractions

4. 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.

Ratios and Proportions: Definition and Examples

5. Ratios and Proportions: Definition and Examples

Watch this video lesson to learn how ratios and proportions are related. Also, learn how ratios and proportions are used in real life and how you can apply them to yours.

Scientific Notation: Definition and Examples

6. 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.

What is an Absolute Value?

7. What is an Absolute Value?

When we're talking and comparing numbers, we often don't care whether its positive or negative, just how big it is. This is often called the magnitude of a number and we find it by taking the absolute value. Learn all about it here!

What is a Computer Algorithm? - Design, Examples & Optimization

8. What is a Computer Algorithm? - Design, Examples & Optimization

Modern computers can carry out very complex tasks. Each task consists of well-defined procedures known as algorithms. Learn how computers use algorithms to perform the tasks we expect them to do.

Estimating a Difference by Rounding
