The Dewey decimal system has nothing to do with mathematics, it is a system for the classification of books by subject, used in libraries.

Libraries classify books to allow for easy retrieval. A library can have hundreds upon hundreds of books (if not thousands or millions of books), and the only way for people to be able to find what they need, there has to be a system in place to organize the collection. Classification not only allows for specific titles to be located, but also allows for browsing of the stacks.

The two major classification schemes used in the United States are the Dewey Decimal Classification System, used in most public libraries; and the Library of Congress Classification, used in most academic libraries.
Biological classification consists of seven main taxonomic ranks. These are: Kingdom, Phylum, Class, Order, Family, Genus, and Species. Each of these ranks groups organisms based on shared characteristics in a hierarchical manner.
