- 1.1: Definition of Real Numbers and the Number Line
- Real numbers are the numbers that are normally used in real world math problems. A line that extends horizontally with coordinates that correspond to real numbers is a number line.
- 1.2: Number comparisons using < ,>, and =
- The number line is to compare numbers.
