A set is a well-defined collection of distinct objects, considered as an object in its own right. The objects in a set are called its elements or members. Sets can contain anything: numbers, letters, symbols, or even other sets. Sets are usually denoted by curly braces {}.
Examples of Sets:
-
Set of Natural Numbers Less Than 5: \[ A = {1, 2, 3, 4} \]
-
Set of Vowels in the English Alphabet: \[ B = {a, e, i, o, u} \]
-
Set of Primary Colors: \[ C = {red, blue, yellow} \]
These examples illustrate how sets can consist of numbers, letters, or items from a specific category.
