What is an empty set in math?

A set is a well-defined collection of numbers, alphabets, objects, or any items. A subset is a part of the set.

Answer: An empty set is a set with no elements.

Let's understand the properties of an empty set.

Explanation:

The empty set is a set with no elements. It is denoted by { } or the symbol Ø.

• An empty set is a subset of every set.
• This implies, { } is a subset of every set.

Thus, the empty set is a set with no elements.
