**Integer no. Line**

**Number Line**

**Writing numbers down on a Number Line makes it easy to tell**

which numbers are bigger or smaller.

which numbers are bigger or smaller.

The Number Line

__Negative Numbers (-)____Positive Numbers (+)__*(The line continues left and right forever.)*

**Numbers on the left are smaller than numbers on the right.**

## Examples:

**5** is smaller than **8****−1** is smaller than **1****−8** is smaller than **−5**

**5**is smaller than**8****−1**is smaller than**1****−8**is smaller than**−5****An Example**

Example: John owes $3, Virginia owes $5 but Alex doesn't owe anything, in fact he has $3 in his pocket. Place these people on the number line to find who is poorest and who is richest.

**Having money**in your pocket is

**positive**.

But

**owing money**is

**negative**.

So John has "−3", Virginia "−5" and Alex "+3"

Now it is easy to see that Virginia is poorer than John (−5 is less than −3) and John is poorer than Alex (−3 is smaller than 3), and Alex is, of course, the richest!

Absolute Value

Absolute Value means to think only about

**how far**a number is from zero.
