Module 1 – Introduction and Review

Section 1.1 – The Real Number System

The Real Numbers include positive and negative counting numbers as well as all their possible ratios (fractions), but that's not all. In order to describe physical measurements we also need to consider "irrational numbers".
In this section you will be reminded why these are necessary and how such numbers all correspond to points on a "Number Line". You will also review the basic arithmetic operations and some of their algebraic properties.
