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
