# Basic Algebra/Working with Numbers/Integers and the Number Line

## Vocabulary[edit]

- Integer
- A whole number (both positive and negative).
- Number Line
- a line marked periodically with numbers
- Origin
- Zero (0)

## Lesson[edit]

An integer is any number, positive or negative, that does not have a fraction or decimal point. Integers can be shown on a number line, like the one below.

This number line shows the numbers from -10 to (positive) 10. Notice the arrows on either side to show that the numbers continue in both directions even though they are not shown on the line.
