There are two ways of describing, or specifying the members of, a set. One way is by intensional definition, using a rule or semantic description:
The second way is by extension - that is, listing each member of the set. An extensional definition is denoted by enclosing the list of members in curly brackets:
1.listing methods 2.roster methods
method in wrinting a set
The two primary methods of writing set notation are roster form and set-builder notation. Roster form lists the elements of a set explicitly, enclosed in curly braces (e.g., A = {1, 2, 3}). Set-builder notation, on the other hand, describes the properties or conditions that define the elements of the set, typically expressed as A = {x | condition}, where "x" represents the elements that satisfy the specified condition.
There are four nouns in that sentence: writing, speaking, methods, and communication.
method of concerning
method of concerning
You either list the elements, or you specify a rule fulfilled by all elements of the set (and only by them).
1. listing method i.e A = {1, 2, 3, 4, 5} 2. set builder notation i.e B = {x | 1 < x < 10 and 3 | x}

The two methods for naming sets are the roster method and the set-builder notation. The roster method lists all the elements of a set within curly braces, such as ( A = {1, 2, 3} ). In contrast, set-builder notation describes the properties or rules that define the elements of a set, such as ( B = { x \mid x \text{ is an even number}} ). Both methods effectively communicate the contents of a set in different ways.
Two methods exist for writing text to a document, and both are methods of the document object.document.write(expr) will print the value of exprto the page.document.writeln(expr) will do the same thing, plus add a newline character at the end.
