What is the difference between a proper subset and only subset?

Sia ? 4 years, 7 months ago

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. The set C={1,3,5} is a subset of A, but it is not a proper subset of A since C=A.
