cardinality of cartesian product calculator

Cartesian product is the product of any two sets, but this product is actually ordered i.e, the resultant set contains all possible and ordered pairs such that the first element of the pair belongs to the first set and the second element belongs to the second set.Since their order of appearance is important, we call them first and second elements, respectively. In set theory, the cartesian product of two sets is the product of two non-empty sets in an ordered way. , 3} {2, Check to make sure that it is the correct set you typed.
