What is the Cardinality of a Set? | Set Theory, Empty Set

What is the cardinality of a set? In this video we go over just that, defining cardinality with examples both easy and hard. To find the cardinality of a set, you need only to count the elements in the set. The cardinality of the empty set is 0, the cardinality of the set A = {0, 1, 2} is 3. The cardinality of a set A is written |A|.
