U146

U146 is a designation used in the context of the Universal Decimal Classification (UDC) system, which is a standardized system for organizing and retrieving information. The UDC is a hierarchical classification scheme that assigns a unique number to every concept, making it easier to locate and retrieve information from libraries, databases, and other information systems.

The UDC system is divided into ten main classes, each represented by a single digit. The first digit of the UDC number indicates the main class, and subsequent digits provide more specific classifications. For example, the number 146 in the UDC system specifically refers to the subject of "Mathematics."

Under the main class of Mathematics (1), the number 146 is further divided into subclasses that cover various areas of mathematical study. These subclasses include algebra, geometry, trigonometry, calculus, and other related fields. The UDC system allows for precise and consistent classification of mathematical knowledge, facilitating efficient information retrieval and organization.

The UDC system is widely used in libraries, archives, and information management systems around the world. Its universal nature ensures that information can be classified and retrieved consistently across different languages and cultures. The UDC is maintained and updated by the International Federation for Documentation (FID), which oversees the development and standardization of classification systems.
