How to find the cardinal number of a set ? Here we are going to see how to find the cardinal number of a set. Cardinal number of a set : The number of elements in a set is called the cardinal number of the set. The cardinal number of the set A is denoted by n(A).

- Two sets have the same cardinal number if and only if there is a bijection between them. In the case of finite sets, this agrees with the intuitive notion of size. In the case of infinite sets, the behavior is more complex. A fundamental theorem due to Georg Cantor shows that it is possible for infinite sets to have different cardinalities, and in particular the set of real numbers and the set
- There are two approaches to cardinality – one which compares sets directly using bijections and injections, and another which uses cardinal numbers. The cardinality of a set is also called its size , when no confusion with other notions of size [2] is possible.
- An Ordinal Number tells us the position of something in a list. 1st, 2nd, 3rd, 4th, 5th and so on (see Cardinal and Ordinal Numbers Chart for more.) Example: In this picture the girl is 2nd :
- The cardinal number of a set is the number of elements in the set. Example: the cardinal number of the set {6, prune, 675, biscuit, London} is 5, since the set contains five … elements. If a set contains repeated elements, they should only be counted once.
