1) A ⊂ A (เซตทุกเซตเป็นสับเซตของตัว

1.) A ⊂ A (set all set as minced set itself).2.) A ⊂ U (set all set as minced in a set of relative universe.)Ø 3) ⊂ A (the empty set is the set of all sets of hack).4. If A, then A ⊂) ø = ø.5. If A ⊂ B and B) ⊂ C, then A ⊂ C (treasure of inheritance).6) A = B ⊂ A and B when B ⊂ A.7. A number of members has n) if the stabilizers set of sets will have a total of 2n hack set.

1) A ⊂ A (sets, each set is a subset of itself)
2) A ⊂ U (set every set is a subset of the universe relative)
3) Ø ⊂ A (empty set is a subset of every set)
4). If a ⊂ ø then a = Ø
5) If a ⊂ B and B ⊂ C, then a ⊂ C (property transfer)
6) a = B if a ⊂ B and B ⊂ a
7) If a has a number n. a subset of a subset of a subset 2n.
