Binary Relations

A binary relation is a way to describe a connection or relationship between pairs of items. For instance, consider two sets: A (like people) and B (like hobbies). A binary relation between these sets might show which people enjoy which hobbies. Examples include "is a friend of" or "is older than". Relations can be represented in various forms, such as tables or graphs. They help us understand how different items relate to one another and are fundamental in fields like mathematics, computer science, and social sciences.
