How do you identify a proper subset?

Set A is a proper subset of set B (A ⊂ B) if all of the elements of set A are members of set B, but there is at least one element of set B that is not an member of set A (A ≠ B). Since all of the members of set A are members of set D, A is a subset of D. Symbolically this is represented as A ⊆ D.

Can a set be a subset and a proper subset at the same time?

A proper subset is one that is a subset of A but not equal to A. So yes a set can be both a subset and a proper subset.

Is belong to and a subset the same?

A is a subset of B means that every element of A is also an element in B. x belongs to A if x is an element of A itself. Example: A={1,2,3} is a subset of B={1,2,3,4}, because 1,2 and 3 are all elements of B. However, 2 belongs to B, and 4 does not belong to A.
