What is a Subset?

A subset is a set that contains only elements that are also in another set. In other words, every element of a subset is also an element of the original set. For example, if we have a set A = {1, 2, 3, 4} and a set B = {2, 3}, set B is a subset of set A because all the elements of B are also elements of A.

Proper Subset

A proper subset is a subset that is not equal to the original set. In other words, for set A to be a proper subset of set B, it must be a subset of B, but not equal to B. For example, if we have a set C = {1, 2} and a set D = {1, 2, 3}, set C is a proper subset of set D because C is a subset of D but C is not equal to D.

Representation

There are various ways to represent subsets, including using set notation or listing the elements of the subset within curly braces. For example, if we have a set E = {1, 2, 3} and a subset F = {1, 2}, F can be represented as F ⊆ E or F = {1, 2}.
