Representing Numbers on a Number Line

Positive numbers are greater than 0. They may be written with a positive sign, but are usually written without it. For example, a gain of 5 yards in football can be written like +5 or 5.  

Negative numbers are less than 0. They are always written with a negative sign (-).   For example, a temperature of 10 degrees below zero is written as -10^o.

You can graph positive and negative numbers on a number line. The positive numbers are to the right of zero and the negative numbers are to the left of 0.
