In mathematics, a **relation** is a way to describe a relationship between sets. Formally, a relation can be defined as a subset of the Cartesian product of two sets. If we have two sets, \\( A \\) and \\( B \\), the Cartesian product \\( A \\times B \\) consists of all possible ordered pairs \\( (a, b) \\) where \\( a \\) is in set \\( A \\) and \\( b \\) is in set \\( B \\).
