Introduction to Sets

The idea of a set is to represent, refer to, and use a collection of objects by treating the set as a single entity, which means a single mathematical object. The objects in such a collection are said to be its elements or members. If a collection of distinct elements is well-defined“Well defined” means that the criteria to determine whether a particular object is in the collection is crisp and unambiguous. and there’s no order among its members, we call it a set.
