2. A ∩ B -- intersection -- objects that belong to set A and set B
3. A ∪ B -- union -- objects that belong to set A or set B
4. A ⊆ B -- subset -- A is a subset of B. set A is included in set B
5. A ⊂ B -- proper subset -- A is a subset of B, but A is not equal to B.
6. A ⊄ B -- not subset -- set A is not a subset of set B
7. A ⊇ B -- superset -- A is a superset of B. set A includes set B
8. A ⊃ B -- proper superset -- A is a superset of B, but B is not equal to A.
9. A ⊅ B -- not superset -- set A is not a superset of set B
10. P(A) -- power set -- all subsets of A
11. a ∈ A -- element of -- set membership
12. x ∉ A -- not element of -- not set membership
13. Ф -- empty set -- { } = Ф
Hope it helps! :D
