Roster method and set-builder notation.
Example of Roster Method
Example of Set-builder Notation:

The Description Form, Roster Form, and The Set-Builder Notation Form.
In mathematics, a set can be named using various methods: by listing its elements within curly braces (e.g., ( A = {1, 2, 3} )), by describing its properties or characteristics (e.g., ( B = { x \in \mathbb{R} \mid x > 0 } )), or by using set-builder notation to define the set based on a condition (e.g., ( C = { n \in \mathbb{Z} \mid n \text{ is even} } )). Additionally, sets can be referenced by capital letters (like ( A, B, C )) or specific symbols to represent particular types of sets (such as ( \mathbb{N} ) for natural numbers).
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. See this example: A is the set whose members are the first four positive integers. B is the set of colors of the French flag. The second way is by extension, that is, listing each member of the set. An extensional definition is notated by enclosing the list of members in braces: C = {4, 2, 1, 3} D = {blue, white, red}

describing of one object
The Description Form, Roster Form, and The Set-Builder Notation Form.
The set of all x which are answers to a particular problem. The set of all ordered pairs, (x,y), which are solutions to an equation of 2 variables.
a.Roster Method:By listing ex:A={1,3,5,7} b.Rule Method:By describing/defining ex:A={the first odd numbers}

Set operations in mathematics refer to the various ways in which sets can be combined or manipulated. The primary set operations include union (combining elements from two sets), intersection (finding common elements between sets), and difference (elements in one set that are not in another). Additionally, the complement of a set represents all elements not in the set, while Cartesian products combine elements from two sets to form ordered pairs. These operations are fundamental in set theory and have applications across various fields of mathematics.
