Interval notation is a method of writing down a set of numbers. Usually, this is used to describe a certain span or group of spans of numbers along an axis, such as an x-axis. However, this notation can be used to describe any group of numbers.

An inequality showing the set of all real numbers greater than -6 and less than or equal to 14 is:

`-6ltxlt=14`

In interval notation it is represented by `(-6,14 ]` .

Notice that there is a round, an exclusive bracket on the left of this interval notation next to -6. This means that this group of numbers continues for values greater than -6. The square bracket on the right next to 14 is an inclusive bracket.  This means that the numbers in this group have values up to 14, and including 14.
