The symbol "⊂" means "is a proper subset of". Example. 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. Note that A ⊆ D implies that n(A) ≤ n(D) (i.e. 3 ≤ 6).

What's the difference between element and subset?

Each object in a set is called an element of the set. Two sets are equal if they have exactly the same elements in them. A set that contains no elements is called a null set or an empty set. If every element in Set A is also in Set B, then Set A is a subset of Set B.

What is the difference between subset and belongs to with example?

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.

What's the difference between a set and subset?

Subsets are a part of one of the mathematical concepts called Sets. A set is a collection of objects or elements, grouped in the curly braces, such as {a,b,c,d}. If a set A is a collection of even number and set B consists of {2,4,6}, then B is said to be a subset of A, denoted by B⊆A and A is the superset of B.
