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.
a=[x;x2,4,6]
x/x g < 18
roster method is just like listing method
The exponential notation and standard notation for 2x2x2x2x2 is:2532
It is just the number written out as we normally write it.Example #1: for the number 725:Standard Notation = 725Scientific Notation = 7.25 x 102Expanded Notation = 700 + 20 + 5Number And Word Notation = 7.25 hundredExample #2: for the number 365.23:Standard Notation = 365.23Scientific Notation = 3.6523 x 102Expanded Notation = 300 + 60 + 5 + .2 + .03Number And Word Notation = 3.6523 hundred
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.
The Description Form, Roster Form, and The Set-Builder Notation Form.

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.
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}.
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}
x/x g < 18
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 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.
