A set is a repertoire of objects, points or signs which are clearly defined. The individual objects in a collection are called the members or elements of the set.

The adhering to table shows some collection Theory Symbols. Scroll down the page for more examples and also solutions of how to usage the symbols.


A set must be properly defined so that us can find out whether an item is a member the the set.

1. Listing The aspects (Roster Method)

The collection can be identified by listing all its elements, be separated by commas and enclosed within braces. This is dubbed the roster method.

Examples:V = a, e, i, o, u B = 2, 4, 6, 8, 10 X = a, b, c, d, e

However, in some instances, it may not be possible to list all the elements of a set. In such cases, we might define the set by methods 2 or 3.

2. Explicate The Elements

The set can be defined, where possible, by explicate the elements clearly in words.

Examples: R is the collection of multiples the 5. V is the collection of vowels in the English alphabet. M is the collection of month of a year.

3. Description By set Builder Notation

The collection can be characterized by describing the aspects using mathematics statements. This is referred to as the set-builder notation.

Examples: C = x : x is an integer, x > –3 This is check out as: “C is the collection of elements x such that x is an integer higher than –3.”

D = x: x is the capital city that a state in the USA

We should define a specific property which all the elements x, in a set, have in usual so that we have the right to know whether a specific thing belongs come the set.

We said a member and a set using the price ∈. If things x is an aspect of collection A, we create xA. If an object z is no an element of collection A, we create zA.

∈ denotes “is an aspect of’ or “is a member of” or “belongs to”

∉ denotes “is no an facet of” or “is not a member of” or “does no belong to”

Example:If A = 1, 3, 5 climate 1 ∈ A and also 2 ∉ A

Basic Vocabulary offered In set Theory

A collection is a arsenal of distinct objects. The objects deserve to be called aspects or members that the set.

A set does not list one element much more than once due to the fact that an element is either a member of the collection or the is not.

There room three main ways to identify a set:

A written description,List or Roster method,Set builder Notation,

The empty collection or null collection is the set that has no elements.

The cardinality or cardinal number of a set is the number of elements in a set.

Two set are equivalent if they contain the same number of elements.

Two sets are equal if castle contain the precise same elements although your order deserve to be different.

Definition and also Notation provided For Subsets and also Proper Subsets

If every member of set A is likewise a member of set B, then A is a subset that B, we create A ⊆ B. Us can also say A is had in B.

If A is a subset the B, however A is not equal B then A is a appropriate subset of B, we create A ⊂ B.

The empty set is a subset of any kind of set.

If a set A has n aspects that it has 2n subsets.

How To usage Venn Diagrams To display Relationship between Sets And set Operations?

A Venn chart is a visual diagram that mirrors the partnership of sets v one another. The collection of all elements being taken into consideration is referred to as the universal collection (U) and is stood for by a rectangle. Subsets that the universal collection are represented by ovals in ~ the rectangle.

The match of A, A", is the collection of aspects in U that is not in A.

Sets space disjoint if they do not share any type of elements.

The intersection of A and also B is the collection of elements in both set A and set B.

The union that A and B is the collection of facets in either set A or collection B or both.
