Set theory
Across
- 4. The first of the transfinite cardinal numbers.
- 5. is the unique set having no elements
- 7. the set theory symbol for the smallest infinite set larger than. (Aleph-0), which in turn is equal to the cardinal number of the set of countable ordinal numbers.
- 9. the set of all ordered pairs (x, y) such that x belongs to A and y belongs to B.
- 11. includes the set of real numbers ® and the set of pure imaginary numbers.
- 12. those elements in A or B, but not in both A and B.
- 13. A set that contains all the subsets of a given set along with the empty set
- 14. a set of elements in the universal set that is not part of the original set
- 15. When a point, object, or number does not belong to a specified set
Down
- 1. the number of elements in a given mathematical set.
- 2. is used in mathematical set theory to indicate that a point, object, or number belongs to a certain set
- 3. a pair of objects
- 6. the set of elements contained in a given set that are not elements of another specified set.
- 8. the union of the set of rational numbers (Q) and the set of irrational numbers
- 10. is a set which contains all objects, including itself
