In this lesson, we will learn:

- Understanding Integers
- Representation of Integers
- Locating Integers on a Number Line
- Comparing Integers Using Inequality Symbols

- Integers include all the whole numbers and their negative selves.
- Whole numbers: all natural numbers including 0.
- Natural numbers: 1, 2, 3, …
- Number line:
- Can be either vertical or horizontal.
- Values in between intervals must be constant (not necessarily 1).
- Numbers increase in value as we move up/right.

- Inequality symbols:
- >: greater than
- <: less than
