Sets

Step-by-step explanation:

1) Set can be defined as a collection of objects that are well defined and distinct.

2) Since each idea has its own unique value or characteristic, they can be considered as objects.

3) Thus, a collection of ideas can be considered as a set.

4) In this case we would define the null set as the set with no ideas.

5) The sets can be represented with the help of curly brackets { }.

6) We can represent it in the set form as:

{Idea 1, Idea 2, Idea 3, Idea 4,...}

7) It can be considered a countable set as we can always count the number of ideas.

8) It is a finite set.
