What is a decimal-numeric system?

• A. Based on hexadecimal categories and subunits.
• B. Based on 10 general categories with 10 parts and 10 subunits at each level.
• C. It uses all-numeric system with no subdivisions.
• D. It is identical to alphabetical filing.

Answer: (B)

A decimal-numeric system is a base-10, hierarchical way of organizing topics where each level is divided in tens and can be refined further by adding more digits. It starts with ten broad categories, each of which has ten parts, and each of those ten subunits can itself be subdivided into ten more, and so on. This structure lets you move from a broad area to a precise topic simply by extending the numeric code, keeping the overall order intact. That’s precisely what the description is conveying: a ten-by-ten-by-ten framework that can be extended with digits to specify increasingly detailed classifications. Why this fits better than the others: a hexadecimal system uses base-16 rather than ten, so it wouldn’t match the ten-part divisions. A completely numeric system with no subdivisions wouldn’t provide the refinement needed for precise categorization. Alphabetical filing relies on letters, not digits, so it isn’t a decimal-numeric approach.
