A set S is said to be a subset of set T if the elements of set S belong to set T, or you can say each element of set S is present in set T. Subset of a set is denoted by the symbol (⊂) and written as S ⊂ T. We can also write the subset notation as; According to the equation given above, “S is a subset of T only if “p” is an element of S as well as an element of T.”Each set is a subset of its own set, and a void set or empty set is a subset of all sets. The sets do not have to have the same exact elements, just the same number of elements. Venn diagrams are generally elements of the sets represented in a circle. And if A = {set of even numbers} and B = { set of natural numbers} the A ≠ B, because natural numbers consist of all the positive integers starting from 1,2,3,4,5 to infinity, but even numbers start with 2,4,6,8, and so on.

Ling 310, adapted from UMass Ling 409, Partee lecture notes March 1, 2006 p. 4 Set Theory Basics.doc 1.4. To denote that A is a proper sub set of B we use the notation A⊂B. Weisstein, Eric W. "Set Difference." '≡' is a symbol of formal logic where, given two propositions a and b, a ≡ b means (a => b AND b => a). Union, Intersection,Difference and Complement of Sets-. . In Mathematics, sets are defined as the collection of objects whose elements are fixed and can not be changed. The set with no element is the empty set; a set with a single element is a singleton.A set may have a finite number of elements or be an infinite set. Basic - The union of two sets A and B is defined as the set of elements that belong to either A or B, or possibly both, whereas the intersection of two sets is defined as the set of elements that belong to both A and B.; Symbolic Representation - The union of two sets is represented by the symbol "∪", whereas the intersection of two . The union of two sets is represented by ∪. The set difference is defined by Here, the backslash symbol is defined as Unicode U+2216. Venn diagrams make it easier to understand the difference and similarities between the sets. Basically, in our day to day life, sets are used to represent bulk data and collection of data. For Example: set A = {2,3,7} and set B = {2,4,9}, The difference between set S and set T is such that it has only those elements which are in the set S and not in the set T. S – T = {p : p ∊ S and p ∉ T}, Let U be the universal set and let A ⊂ U. Subset, strict subset, and superset. . Complement of a Set: Symbol, Difference, Venn Diagram. Let Y = {Zoya, Rahul, Riya} be the set of students from Class XI who are in the school football team. The difference resides above all in the level at which the two concepts are introduced. When $U = \mathbb{R}$, $\overline{\mathbb{Q}} = \mathbb{R} \setminus \mathbb{Q}$. Set notation also helps us to describe different relationships between two or more sets using symbols. jade plays Tennis and Volleyball.
