Set theory
Across
- 3. Also known as the disjunctive union, is the set of elements which are in either of the sets, but not in their intersection.
- 7. Is the set of all elements in the collection
- 8. Is the set theory symbol for the smallest infinite set larger than.
- 10. A pair of elements a, b having the property that ( a, b) = (u, v ) if and only if a = u, b = v.
- 12. Often denoted by Aᶜ, are the elements not in A.
- 13. A collection of elements
- 14. the set containing all elements of A that also belong to B
- 15. Is a number such as −3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.
Down
- 1. Is a number that can be expressed in the form a + bi, where a and b are real numbers, and i represents the “imaginary unit”, satisfying the equation i2 = -1.
- 2. Of a set is a measure of the "number of elements" of the set
- 4. Is a value of a continuous quantity that can represent a distance along a line
- 5. Is colloquially defined as a number that can be written without a fractional component
- 6. Is a set which contains all objects, including itself.
- 9. Is the smallest infinite number.
- 11. Is the unique set having no elements; its size or cardinality is zero.
