## What is Interval Notation Calculator?

An interval is all the numbers between two given numbers. There are three types of interval   1.Open interval    2.Closed interval    3. Half open interval

Open interval: This type of interval does not include the endpoints of the inequality. For example (1, 3) indicates numbers between 1 and 3 excluding 1 and 3

Closed Interval: This type of interval includes the endpoints of the inequality. For example [1, 3] indicates numbers between 1 and 3 including 1 and 3

Half-open interval: This type of interval includes only one of the endpoints of the inequality. For example [1, 3) indicates numbers between 1 and 3 including only 1.

### Solved Example:
