Integers and Absolute Value - Adv.

Introduction to Integers & Absolute Value

What is an integer?

Integers are:

The set of whole numbers and their opposites.

Examples: -2, 5, 0, -1

Ordering Integers

How do you order integers?

The bigger the negative number, the smaller the value is. This is because the number is further away from 0.

For example: -2 is smaller than -1.

Absolute Value

What is absolute value?

• The absolute value of a number is the distance away from zero on the number line.

• You can never have a negative absolute value. Absolute value can only be positive.

Comparing absolute value

How to compare absolute values:

When you are comparing two absolute values, remember that there is never a negative absolute value. Compare the two numbers as if they are both positive numbers.

Match

Compare the following absolute values:

<

=

>

>

• <

• =

• >

• >

Opposites

What is an opposite?

• The opposite of a number is the same distance away from zero but always on the other side of the number line.

• It can be either positive or negative.

For example:
The opposite of 1 is -1. The opposite of -3 is 3.
