What is a set and subset in math?

A set A is a subset of another set B if all elements of the set A are elements of the set B. In other words, the set A is contained inside the set B. The subset relationship is denoted as A⊂B.

How do you describe subsets and sets?

A set is a well-defined collection of objects. Each object in a set is called an element of the set. Two sets are equal if they have exactly the same elements in them. If every element in Set A is also in Set B, then Set A is a subset of Set B.
