That is called the UNION of the two sets.
If all elements of set A are also elements of set B, then set A is a subset of set B.
a set having no elements, or only zeros as elements.
Those are called the elements of the set.
A set is a collection of objects called ELEMENTS OR MEMBERS.
Members.
Empty set or null set
That is called the average or mean.
a set which has no elements in it is called a null set. example - A={}.
This is called the complement of the set.

In mathematics, a finite set is a set that has a finite number of elements. For example, (2,4,6,8,10) is a finite set with five elements. The number of elements of a finite set is a natural number (non-negative integer), and is called the cardinality of the set. A set that is not finite is called infinite. For example, the set of all positive integers is infinite: (1,2,3,4, . . .)
It's called an infinite set.
A function, f, is usually a mapping from a set of input values. This set, whose elements are often denoted by x, is called the domain.A function, f, is usually a mapping from a set of input values.

Each family of elements has its own set of characteristics that each of the elements possess.
