## Representing set difference using Venn diagram

In this chapter we will learn to represent set difference operation using Venn diagram. Let’s first review the basics of set difference operation. What is Difference of set ? Let there are two sets A & B. The difference of set A – B will result in elimination of common elements of set A & …

## Disjoint sets Venn diagram

In this chapter we will learn to represent disjoint sets using Venn diagram. Let’s first review the basics of disjoint sets. What are disjoint sets? Two sets are said to be disjoint if there are no common elements between the two. The disjoint sets after intersection will return an empty set. If A & B …

## Union of sets – Venn diagram

In this chapter we will learn to represent union of sets using Venn diagram with examples. Let’s first review the union operation in set theory. What is Union in set theory ? If A & B are two sets, then union operation will result in element present in both set A & B. For Example;If …

## Venn Diagrams in Set theory

In this chapter we will learn to use Venn diagram in set theory with solved examples. Using Venn Diagrams in set theory Using Venn diagram we will graphically represent different sets in the form of pictures. In Venn diagrams;⟹ universal set U is represented by points in rectangular box ⟹ the subsets of U are …

## Power Set

In this chapter we will understand the concept of power set with properties and examples. To understand power sets, you should have good understanding about the subsets and its properties. Read about the subsets here. What are Power sets ? Power set is a collection of all subset of a given set. If A is …

## Equal and Equivalent set

In this chapter we will learn about the definition of equal and equivalent sets with properties and solved examples. Equal sets Two sets A & B are equal when both the sets have same elements. This means that every element of set A is a member of B and every element of set B is …

## Finite and Infinite sets

In this chapter we will learn the difference between finite and infinite sets with properties and examples. Finite Set definition A set is said to be finite set if its elements can be counted by natural numbers. This mean that the number of element of finite set is finite and gets over after certain point. …

## Set Theory

In this chapter we will learn the basics of set theory with representation, properties and examples. What is a set ? Set is a collection of elements. The elements can be number, letters, words or symbols. You can imagine a set as a container which contain different elements. Examples of Set Some common examples of …

## Cardinal Number of set

In this chapter we will learn the definition of cardinal number of set with method of calculation and solved example. What is Cardinal number of set? The number of distinct element present in a set is called cardinal number of set. For Example;Consider the set A with following elements.A = { 2, 5, 7, 9 …

## Difference of Sets

What is Difference of sets? If A & B are given two sets, then the difference of set A & B will results in: ⟹ removal of common element between A & B from set A ⟹ only the unique element of set A will remain after subtraction. For ExampleGiven below are sets A & …
