In mathematics, a cardinal number, or cardinal for short, is what is commonly called the number of elements of a set. In the case of a finite set, its cardinal number, or cardinality is therefore a natural number.
Cardinal numbers are natural numbers or positive integers. The smallest cardinal number is 1. Examples of cardinal numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, and so on.
The meaning of CARDINAL NUMBER is a number (such as 1, 5, 15) that is used in simple counting and that indicates how many elements there are in an assemblage.
The number of elements or members in a set is the cardinal number of that set. If A is a finite set and it has elements equal to N. Then the cardinal number of set A is N.
Cardinal numbers are numbers that represent the number of items(quantity) while ordinal numbers represent the rank or position of an item in the given list. What is a Cardinal Number in Sets? In set A, if there are a total of 25 elements then 25 is the cardinal number of set A represented by n(A).

Apr 10, 2018 · The cardinal number $ \gamma $ is the product of $ \alpha $ and $ \beta $, written as $ \gamma = \alpha \beta $, if and only if every set of cardinality $ \gamma $ is equivalent to the Cartesian product $ A \times B $ of sets $ A $ and $ B $, where $ \mathsf {card} (A) = \alpha $ and $ \mathsf {card} (B) = \beta $.
