**What is the symbol for the universal set?**

A **universal set** is a **set** which contains all the elements or objects of other **sets**, including its own elements. It is usually denoted by the **symbol** ‘U’. (There is no standard notation for **Universal set symbol**, it can also be denoted by any other entity like ‘V’ or xi).

Similarly, it is asked, what does ∈ mean?

**∈** (mathematics) **means** that it is an element in the set of… For eg x **∈** ℕ denotes that x is within the set of natural numbers. The relation “is an **element of**“, also called set membership, is denoted by the symbol “**∈**“. Equivalent expressions are “x is a member of A”, “x belongs to A”, “x is in A” and “x lies in A”.

Beside above, what do the set symbols mean? An element or member of a **set** is an object that belongs to the. **set**. The **symbol** ∈ **means** “is an element of” The **symbol** /∈ **means** “is not an element of” Generally capital letters **are** used to represent **sets** and lowercase.

Thereof, how do you find the universal set?

**A universal set is the set of all elements under consideration, denoted by capital U or sometimes capital E.**

- Example: Given that U = {5, 6, 7, 8, 9, 10, 11, 12}, list the elements of the following sets.
- Solution: The elements of sets A and B can only be selected from the given universal set U .
- Example:
