Basically two ways: either by listing all the elements, or by specifying some rule for elements to be included. Listing all the elements only makes sense for finite sets.
(1) List the elements, and (2) Define a rule that elements of the set must fulfill.
You can specify a set either by listing all of its members (not an option for sets that are very large or even infinite), or by specifying some rule for elements to be a part of the set.
Let's say the set S has n elements. An element can be either in the subset or not in the subset. So There are two ways for one element. Therefore the number of subsets of a set of n elements is 2 multiplied n times which is 2^n
in a set if two elements or numbers are equal then it is known as equivalent set

The structure of army writing is simple and consists of which two elements?

The chemical symbols are approved by IUPAC; symbols are derived from the name of the chemical element in Latin, frequently the first two letters.
That is called the UNION of the two sets.

The set of elements that are elements of the two (or more) given sets is called the intersection of the sets.
This set is known as the union of two or more sets, which comprises all unique elements that are present in at least one of the sets. These elements are shared between the sets and are not duplicated within the union set.
The union of a collection of sets is defined as the set of all distinct elements that are in the collection. This includes the specific case where the collection consists of two sets.
Two sets are equal if they have the same elements. Two sets are equivalent if there is a bijection from one set to the other. that is, each element of one set can be mapped, one-to-one, onto elements of the second set.
