Homonym: 集合 (Collection)
集合 (set) is a fundamental concept in mathematics that refers to a collection of distinct objects, considered as an object in its own right. These objects can be anything, such as numbers, letters, or even other sets. The elements of a set are usually denoted within curly braces, for example, 1, 2, 3 represents a set containing the numbers 1, 2, and 3.
In set theory, operations such as union, intersection, and difference can be performed on sets. The union of two sets combines all unique elements from both, while the intersection includes only the elements common to both sets. Understanding集合 is essential for various fields, including computer science, statistics, and logic.
