The Interval Notation Calculator is a free online tool that is made to display the number line for the given interval in the system. The three most popular methods to represent the intervals are namely:

  • Interval Notation Method
  • Number Line Method
  • Inequalities Method

In this method, you must note that the starting and the ending number will be represented using the brackets. It has only two types of brackets, the square bracket and the round brackets.

So, if the interval is mentioned in a square bracket, the end values are included. On the other hand, if the interval is mentioned in round brackets, the end values are not included eventually.

Similarly, the intervals can also be mentioned using inequality functions such as the greater than (>), less than (<), greater than or equal to (<=), less than or equal to (<=).

The steps to use the interval notation calculator is as under:

Step 1: Begin with entering the interval (closed/open interval) in the input fields.

Step 2: Click on the button “Calculate” in order to get the output.

Step 3: The number line for the given interval will be displayed in the new tab.
