Interval notation is a method to represent an interval on a number line. In other words, it is a way of writing subsets of the real number line. An interval comprises the numbers lying between two specific given numbers. Understand interval notation bett
To write in interval notation, use parentheses for opened ends and square brackets for closed ends. The first and last values within the interval are then written within and separated by a comma.What is an Interval? Similar to its English meaning, in Math, an interval can be thought of as...

Interval NotationInterval notation is a simplified way of describing a particular interval. Let’s see how it’s done. Step 1: We write the first and last number of the interval, which are the endpoints of the interval. For example, if the interval is from 6 to 20, we write 6, 20. ...
We use interval notation to represent subsets of real numbers. Suppose that a and b are real numbers such that a < b.Then, the open interval (a,b) represents the set of all real numbers between a and b, except a and b. { x / a < x < b} is the set-builder notation....

More formally, the definition of a closed interval is an interval that includes all of its limits. Notation Intervals are designated by writing the start point and end point as an ordered pair, within brackets. Square brackets show that an endpoint is included in an interval; so the closed ...
Josh has worked as a high school math teacher for seven years and has undergraduate degrees in Applied Mathematics (BS) & Economics/Physics (BA). Let's review. Any set of real numbers can be written in interval notation. There are two types of intervals: open intervals, where neither of ...
