Operation on sets in which the first set is **Union Symbol. **Thus if you have to sets of union **A union B **Than we can write of elements **A ⋃ B = { x: x ∈ A or x ∈ B }**. Hence this is a symbol of the union ‘**⋃**‘** ( Union Symbol ).**

## Union Symbol

Here We have to define sets of union symbols As an example. Accordingly, **A ⋃ B or B ⋃ A.** Just for spite there are two or three can be more than the number of sets like union A1, A2, A3………n sets and B1, B2, B3………n sets.

However, If set A = { 1, 2, 3, 4, 5 } and set B = { 4, 5, 6, 7 } than all elements add in union of A and also add B elements of union.

**As an example**:- A = { 1, 2, 3, 4, 5 } , B = { 4, 5, 6, 7 }

**Result: – ** A ⋃ B = { 1, 2, 3, 4, 5, 6, 7 }.

## A Union B

Thus, we can write another example for **A union B**. By the way, we already define an example related to it in all the above sections. Also still getting another example of a union b.

Let A = { a, b, c, d, e } or B = { d, e, f, g }

**Solution:- **A ⋃ B = { a, b, c, d, e, f, g }

Here you can see this example. there are two sets of union A and B. Also available some properties of sets a and b in which we define with the sets like a, b, c, d…n sets.

Therefore, It means one element all properties and another element all properties of unique properties to match in the union. Finally, this is the right example of **A union b **with the use of the union symbol.

### Set Symbols Math

Symbols | Meaning of symbols |

{} | Set |

A ∪ B | Union |

A ∩ B | Intersection |

A ⊆ B | Subset |

A ⊂ B | Proper Subset |

A ⊄ B | Not a Subset |

A ⊃ B | Proper Superset |

A ⊇ B | Superset |

A ⊅ B | Not a Superset |

∀ | for all |

## Intersection Symbol ( Union Symbol )

Here set of intersection symbols in which symbol A ⋂ B. Similarly, It means A elements should be too available set A and also should be available set B that is an intersection. Hence this is a symbol of the intersection ‘⋂’** ( Intersection Symbol ).**

Let:- **A ⋂ B = { x: x ∈ A and x ∈ B }**

As an example, we can write an example for the **intersection symbol **with the using set of elements A and B. After that, find this it s useful Python Pass

A = { 1, 2, 3, 4, 5, 6 } and B = { 4, 5, 6, 7, 8 }

**Solution:-** A **⋂ **B = { 4, 5, 6 }

As a rule, there are two sets of elements A and B. In which element we implement intersection can see all the above sections. Accordingly, each set properties element available both sets A and b such as we define intersection example.

### Union and Intersection Examples

Usually, We have implemented some examples of union and intersection with both. As we know we have to take three sets of elements. As an example, A = { 1, 2, 3, 4, 5 } , B = { 4, 5, 6, 7, 8, 1,2 } and C = { 3, 4, 5, 6 }.

These are set A, B, and C in which n no of properties are available. Therefore we will implement both symbol union and intersection in these examples.

Let:- A = { 1, 2, 3, 4, 5 }

B = { 4, 5, 6, 7, 8, 1, 2 }

C = { 3, 4, 5, 6}

Afterward We imliment this **A ⋃ ( B ⋂ C )**

Therefor:- **A ⋃ ( B ⋂ C ) = { 1, 2, 3, 4, 5 } ⋃ ({ 4, 5, 6, 7, 8, 1, 2 } ⋂ { 3, 4, 5, 6})**

**Step 1** :- A ⋃ ({ 4, 5, 6, 7, 8, 1, 2 } ⋂ { 3, 4, 5, 6})

A ⋃ { 3, 4, 5, 6 }

**Step 2** :- { 1, 2, 3, 4, 5 } ⋃ { 3, 4, 5, 6 }

**As a result** :- { 1, 2, 3, 4, 5, 6 }

## Union Symbol in Word

Here many people don’t know that how to insert **union symbol in word**. Therefor, let me below should be explain where is symbols in word. In this case, to know about union and other set of symbols follow these steps.

- Go to the word pad and should create a page.
- After that go to the menu bar to word and also click the insert button.
- Then find the symbols button on the menu section.
- So there are available union symbol and also available other symbols on the word.
