There are two approaches to cardinality â 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 is possible.
The cardinality of Set A is 4. We would write this as: n(A) = 4. Because Set A and Set B contain the same cardinality, we would write this as: n(A) = n(B). Because the cardinality of sets A and B are equal, sets A and B are equivalent.
