Question

What is set
And proper set ,improper set ,roaster form

Answer 1

Set is a collection of objects but in mathematics, the definition of the set is one of the most strange definitions. It is a way in mathematics that allows us to put similar objects together. A proper subset of a set A is a subset of A that is not equal to A. In other words, if B is a proper subset of A, then all elements of B are in A but A contains at least one element that is not in B.
