Set Theory
Across
- 5. - ⊇\supseteq⊇ (e.g., B⊇AB \supseteq AB⊇A)
- 6. Set - ∅\emptyset∅ or {}\{\}{}
- 7. Subset - ⊂\subset⊂ (e.g., A⊂BA \subset BA⊂B)
- 8. an element of - ∉\notin∈/ (e.g., b∉Ab \notin Ab∈/A)
- 9. Set - UUU (the set that contains all objects under consideration)
- 12. Set - P(A)\mathcal{P}(A)P(A) or 2A2^A2A (the set of all subsets of AAA)
- 13. - AcA^cAc or Aˉ\bar{A}Aˉ (the complement of AAA)
- 14. Product - ×\times× (e.g., A×BA \times BA×B)
- 15. - ∪\cup∪ (e.g., A∪BA \cup BA∪B)
Down
- 1. Sets - ∩=∅\cap = \emptyset∩=∅ (sets with no elements in common)
- 2. - ∖\setminus∖ (e.g., A∖BA \setminus BA∖B)
- 3. - ⊆\subseteq⊆ (e.g., A⊆BA \subseteq BA⊆B)
- 4. Superset - ⊃\supset⊃ (e.g., B⊃AB \supset AB⊃A)
- 5. - {}\{ \}{} (e.g., {a,b,c}\{a, b, c\}{a,b,c})
- 10. - ∩\cap∩ (e.g., A∩BA \cap BA∩B)
- 11. of - ∈\in∈ (e.g., a∈Aa \in Aa∈A)
