Ordinal arithmetic is a branch of mathematical logic that deals with the addition, multiplication, and exponentiation of ordinals. Ordinals are a generalization of natural numbers that extend the concept of "size" or "position" beyond finite sets to infinite sets. They are used to describe the order type of well-ordered sets, which are sets in which every non-empty subset has a least element. ### Basic Concepts 1.
