Subsets in Maths

Subsets in maths are a core concept in the study of Set Theory, similar to Sets. A group of elements, objects, or members enclosed in curly braces, such as {x, y, z} is called a Set, where each member of the set is unique. So for a set of {x, y, z} the possible subsets are {}, {x}, {y}, {z}, {x, y}, {y, z}, {z, x} or {x, y, z}. While defining a set its elements could be real numbers, constants, variables, or any other objects as well.

This article explores the concept of Subsets in detail and makes it easy to grasp for all the readers of the article without any regard to their academic level. All subtopics such as their meaning, definition, symbol, example, and many many more, are covered in the article with plenty of examples. So, let’s start our journey to the land of set theory and understand this concept of Subsets.

In this article, we have provided detailed information about what are subsets in maths, supersets in maths, proper subset, and improper subset with examples and FAQs.

What are Subsets in Maths?

A set ‘A’ is a subset of set ‘B’ if all the elements of set A come under set B. Also, a subset can be equal to a set in a particular case when all the elements of a subset are contained in the set....

Example of Subsets

The only need for a set A to be a subset of a set B is that every element of A be present in B. Here are some instances of subsets based on this....

Power Set of a Set

A set’s power set consists of every subset as well as the original set and the empty set. P(A) stands for the power set of a given set A. For example, If A = {1, 2}, then P(A) = {{ }, {1}, {2}, {1, 2}}. Here we can clearly see that all the subsets of A are contained in the P(A) i.e., power set of A....

Types of Subsets

Proper Subset

A proper subsetonly comprises a few members of the original set. Proper subset can never be equal to the original set. In proper subset the subset forming the original set is excluded....

Improper Subset

An improper subset contains includes both the null set and each member of the initial set. Improper subset can be equal to the original set. In improper subset the subset forming the original set is included. This is represented by the symbol ⊆....
