Enumerate 10 main classes of ddc?

The Dewey Decimal Classification (DDC) is a library classification system that organizes library materials by subject. It is hierarchical, meaning that subjects are divided into increasingly specific categories.

Here are 10 main classes of DDC:

1. 000 Computer science, information, and general works

2. 100 Philosophy and psychology

3. 200 Religion

4. 300 Social sciences

5. 400 Language

6. 500 Pure science

7. 600 Technology

8. 700 The arts

9. 800 Literature

10. 900 Geography and history

It's important to note that this is a simplified overview, as the DDC is much more complex than these 10 classes suggest. Each class is further subdivided into numerous categories and subcategories.
