If a set contains only a portion of another set's elements, it is referred to as a proper subset of the larger set. In the event that two sets share exactly the same elements, they are merely subsets and not classified as proper subsets. The symbol ⊂ is often used to represent a proper subset. A comparison of the elements within the sets is a practical way to identify if one is a proper subset of the other.
