###### Topic Notes

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
