x/x g < 18
a=[x;x2,4,6]
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.
roster method is just like listing method
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}
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.

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}
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.

N={3,4,5,6,7,8}
A list of elements, separated by commas, enclosed in curly braces. Example: {3, 5, 7} is the set of single-digit odd prime numbers.
