A list of elements, separated by commas, enclosed in curly braces. Example: {3, 5, 7} is the set of single-digit odd prime numbers. Tricky Example: { { }, {3}, {5}, {7}, {3,5}, {3,7}, {5,7}, {3,5,7} } is the set of subsets of the set of single-digit odd prime numbers. Notice that every element of this set is itself a set. The roster notation allows the use of nested curly-braces to describe sets which have other sets as elements. Infinite set in roster notation: {1, 2, 3, ...} is the set of positive integers. The first few elements illustrate the pattern, and the ellipsis (three dots) indicate that the pattern continues indefinitely.
There are two ways of writing sets:1. Roster Method-listing the elements in any order and enclosing them with braces.Example:A= {January, February, March…December}B={1,3,5…}2. Rule Method-giving a descriptive phrase that will clearly identify the elements ofthe set.Example:C={days of the week}D={odd numbers}1. Roster Method- listing the elements in any order and enclosing them in a bracket.A = {1, 2, 3, 4}2. Rule Method- giving a descriptive phrase that will clearly identify the elements of the set.A = { first four counting numbers}ang mga batayan sa pagsusulat ng historya ay ang mga mananaliksik. at dahil din sa grupong tinatawag na tropapa.The two methods in writing sets are 1.) Listing method and 2.)Roster method.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}
Roster method: A={1,2,3,4,5,6,7,8}Rule mathod: A={ ✖️.✖️ is a 1-8}
roster method is just like listing method
Sets can be written in various ways, including roster notation, set-builder notation, and interval notation. Roster notation lists all the elements of a set, such as ( A = {1, 2, 3} ). Set-builder notation describes the properties of the elements, like ( B = { x \mid x > 0 } ). Interval notation is often used for sets of numbers, such as ( C = (0, 5] ), indicating all numbers greater than 0 and up to 5.
The Description Form, Roster Form, and The Set-Builder Notation Form.
The first one is roster method or listing method. The second one is verbal description method and the third one is set builder notation.

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.
Roster method and set-builder notation. Example of Roster Method {a, b, c} {1, 2, 3} {2, 4, 6, 8, 10...} Example of Set-builder Notation: {x/x is a real number} {x/x is a letter from the English alphabet} {x/x is a multiple of 2}
The number 1315171921 can be expressed in set builder notation as the set of all individual digits: {1, 2, 3, 5, 7, 9}. Using roster method, this can be written as: {1, 1, 1, 2, 1, 5, 1, 7, 1, 9}. However, to avoid repetition in set notation, we simplify it to {1, 2, 5, 7, 9}.
Sets can be written in two primary ways: roster notation and set-builder notation. Roster notation lists all the elements of the set within curly braces, for example, ( A = {1, 2, 3} ). Set-builder notation describes the properties of the elements that belong to the set, typically in the form ( B = { x \mid x \text{ is an even number} } ). Both methods effectively convey the composition of a set but serve different purposes in mathematical contexts.
there are several ways of representing a set if our collection does not contain a very large Numbers's may use roster notation to describe it.
