Cardinal number
In mathematics, cardinal numbers, or cardinals for short, are a generalization of the natural numbers used to measure the cardinality (size) of sets.

Cartesian product
In set theory (and, usually, in other parts of mathematics), a Cartesian product is a mathematical operation that returns a set (or product set or simply product) from multiple sets.

Combinatorial principles
In proving results in combinatorics several useful combinatorial rules or combinatorial principles are commonly recognized and used.

Combinatorics
Combinatorics is an area of mathematics primarily concerned with counting, both as a means and an end in obtaining results, and certain properties of finite structures.

Disjoint sets
In mathematics, two sets are said to be disjoint sets if they have no element in common.

In mathematics, an ordered pair (a, b) is a pair of objects.

Rule of sum
In combinatorics, the rule of sum or addition principle is a basic counting principle.
