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.

The Number Line between the integers -10 and 10

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.
