Extensional definition. An extensional definition of a concept or term formulates its meaning by specifying its extension, that is, every object that falls under the definition of the concept or term in question.
A set is a collection of distinct, symbols in ordered objects. Sets are typically collections of numbers, though a set may contain any type of data (including other sets).The objects in a set are called the members of the set or the elements of the set.A set should satisfy the following: 1) The members of the set should be distinct. If A and B are two sets, then difference of A and B is the set A-B consisting of all the elements which are elements of A but are not elements of B. 2  Complement of a set A, written as A' or A C is the set consisting of all the elements of which do not belong to A. 3  Thus A' = {x | x and xA}.
