While part 1 of Unit 3 dealt with the roots of numbers, Unit 3: Part 2 deals specifically with types of numbers and exponents. What happens where there is no easy root for a number? How do you deal with those little superscripts¹? This unit will help us to answer these questions.

All resources for this Unit (including Homework and links to the videos in this page) are linked on the Course Modules page in the Unit 3: Part 2 area.

We will be using the videos below as additional resources as we move through this unit. I am including a gallery of the videos embedded here on this page as a quick reference guide. Please review these videos as needed during this unit.

Use these videos in conjunction with class materials - they are great study Materials.

What makes a number rational or irrational? What do these terms mean anyways?

Use the video below to answer these questions and review the difference between rational and irrational numbers.

Introduction to rational and irrational numbers:

Exponents become very important as you move further into math and science as exponents simplify the expression of large numbers. We will be working with basic exponents as well as Scientific notation (a10b) in this unit. Please review the following videos for a quick refresher!

Introduction to exponents:

Scientific notation: Scientific Notation

¹A superscript is a small raised number of letter. These are commonly used to denote footnotes in text; in math superscripted numbers are used to denote exponents.
