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.
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 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.
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}
The elements of a set can be written in two ways: roster form and set-builder notation. In roster form, the elements are listed explicitly within curly braces, such as {1, 2, 3}. In set-builder notation, a property or rule that defines the elements is described, for example, {x | x is a positive integer less than 4}.
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.
