## What is a concept in a theory?

## What is a set that does not contain itself?

## Why is the concept of set important?

The purpose of sets is **to house a collection of related objects**. They are important everywhere in mathematics because every field of mathematics uses or refers to sets in some way. They are important for building more complex mathematical structure.

## What objects contain a set?

The objects in a set are called **the elements (or members ) of the set**; the elements are said to belong to the set (or to be in the set), and the set is said to contain the elements. Usually the elements of a set are other mathematical objects, such as numbers, variables, or geometric points.

## How do you describe a set?

**The elements of a given set must be distinct**.

For example, we should write the set {1,3,5,3,7,9,7} as {1,3,5,7,9}. The order in which the elements are written in a set does not matter. For example, the set {1,2,3,4} can be written as {4,3,2,1}, or {2,4,3,1}. All these sets are the same.
