Answer:
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.
