A null or empty set is a set that does not contain any elements.
null set or empty set, is a set with no elements.
If all the elements in set A are also elements of set B, then set A is a subset of set B.
If you mean null set, that's a set having no elements, or only zeros as elements.
A finite set or a countably infinite set.
a set having no elements, or only zeros as elements.
It depends on what the elements are.
The number of elements. A set with n elements has 2n subsets; for example, a set with 5 elements has 25 = 32 subsets.
Binary relationship, relationship set with abbreviated name, and ternary relationship set are the different kinds of sets. A binary relationship in math terms means that there are ordered pairs.
A proper subset B of a set A is a set all of whose elements are elements of A nad there are elements of A that are not elements of B. It follows, then, that an improper subset must be the whole set, A. That is, A is an improper subset of A
They are collections of some, or all, of the elements of the set. A set with n elements will have 2^n subsets.
A null set.
