What is the roster method?

The term "roster method" refers to a technique in representing a set by directly listing all of its elements, which are separated by commas and enclosed by a pair of curly brackets. The roster method is also referred to as the "tabular form method."

In mathematics, a "set" is defined as a collection of items, known as "elements." It is typically denoted by a capital letter. A set that belongs to another set is called a "subset." In the roster method, all listed elements can be in any order but should be distinct from one another. The "statement form" and "rule or set builder" are two other methods to describe sets.
