How to Write Subset of a Set
http://ItsMyAcademy.com/Set-Theory/ For List of Set Theory Tutorial videos. To write the subset of a given set first we should know what is subset. Subset of a set means the new set made with the elements of the given set. A is subset of B means all the elements of set A is found in set B. set A is completely made with elements of set B. To write the subset , we can make as much as possible sets with the elements of given set. phi and set itself is subset of every set. So we can say there are at least two subset of all set except empty set it self. Empty set has only one subset which is itself.
