So an interval notation is simply a compact way of representing subsets of real numbers using two numbers (left and right endpoints), the comma symbol, parentheses ( ), brackets [ ], and infinity symbols (positive or negative).
An Interval is all the numbers between two given numbers. It is important to show if the beginning and end number are included. There are three main ways to show intervals: Inequalities, The Number Line and Interval Notation.

Interval notation is a notation used to denote all of the numbers between a given set of numbers (an interval). For example, "all of the integers between 12 and 16 including 12 and 16" would include the numbers 12, 13, 14, 15, and 16.
Sep 15, 2021 · Inequalities slice and dice the real number line into segments of interest or intervals. An interval is a continuous, uninterrupted subset of real numbers. How can we notate intervals with simplicity? The table below introduces Interval Notation.
In interval notation, we use a square bracket [ when the set includes the endpoint and a parenthesis ( to indicate that the endpoint is either not included or the interval is unbounded.
An interval is a way of describing a subset of the real numbers between two given values. For example, we can describe the set of positive numbers, 𝑥, that are less than 2 as an inequality: 0 < 𝑥 < 2. The equivalent set in interval notation is ] 0, 2 [, so saying 𝑥 ∈] 0, 2 [ means that it is between 0 and 2.
