In mathematics, a set is a collection of distinct objects, considered as an object in its own right. For example, the numbers 2, 4, and 6 are distinct objects when considered separately, but when they are considered collectively they form a single set of size three, written {2, 4, 6}. The concept of a set is one of the most fundamental in mathematics. Developed at the end of the 19th century, set theory is now a ubiquitous part of mathematics, and can be used as a foundation from which nearly all of mathematics can be derived.

Examples:

{1, 2} ∪ {1, 2} = {1, 2}.

{1, 2} ∪ {2, 3} = {1, 2, 3}.

{1, 2, 3} ∪ {3, 4, 5} = {1, 2, 3, 4, 5}
