What is set?
A set is defined as the grouping of different elements that share similar characteristics and properties with each other . These elements can be anything, such as numbers, songs, months, people, and so on.
In turn, a set can also become an element. For example, a bouquet of flowers. In principle a flower would be the first element, but the set of flowers can then be considered as a bouquet of flowers, thus becoming a new element.

Types of sets
When forming a set, the way and how we group them together can vary, giving rise to different types of sets:
- Finite sets: The characteristic of this set is that its elements can be counted or enumerated in its entirety. For example, the months of the year establish a finite set: January, February, March, April, May, June, July, August, September, October, November and December.
- Infinite set : A set will be infinite when its elements are impossible to count or enumerate in its entirety, because they have no end. Numbers are a clear example of an infinite set.
- Unitary set : One that is composed of a single element. The moon is within this set, as it is the only natural satellite on planet earth.
- Empty set : it is a set which does not present or have elements.
- Homogeneous set : Sets whose elements have the same class or category.
- Heterogeneous set : The elements of these sets differ in class and category.
- Equivalent sets: Those sets whose quantity of elements is the same will be equivalent.
- Equal sets: Two or more sets may be said to be equal, when they are composed of identical elements.
