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 better using solved examples.
In interval notation, the symbol ∩ is used to represent the intersection of two intervals. The intersection of two intervals is the set of all values that are common to both intervals. To find interval notation for a set of numbers, identify the minimum and maximum values of the set, and then use the appropriate symbols to represent the set.
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.

Interval notation is a way to describe continuous sets of real numbers by the numbers that bound them. Intervals, when written, look somewhat like ordered pairs. However, they are not meant to denote a specific point.
