What is the roster method in algebra?

The roster method in algebra is a way of specifying a set by listing its elements explicitly, enclosed in curly braces. For example, the set of even numbers between 1 and 10 can be represented as {2, 4, 6, 8, 10}. This method provides a clear and straightforward way to define small sets, making it easy to understand the elements included. However, it becomes impractical for larger sets or when dealing with infinite sets.
