What is a terminal-digit numeric system?

• A. The first digit is primary.
• B. The last digit or group of digits is the primary unit.
• C. The middle digits are the primary unit.
• D. The system uses letter codes as primary unit.

Answer: (B)

A terminal-digit numeric system organizes and groups items based on the digits at the end of a number. The last digit (or the last few digits) is treated as the primary unit for sorting, scheduling, or filing, rather than the leading part of the number. This approach helps distribute workload and manage processing more evenly because items with the same ending digits end up in the same category, even if the rest of the number varies. For example, in a court docket setting, cases might be assigned to processing groups by the final digit of the citation. If a case ends with 0, it goes into the same group as other cases ending in 0, regardless of the earlier digits. The ending digits drive the grouping, while the other digits are still part of the identifier but are not the primary organizing factor. The other ideas describe different schemes: using the first digit as the main unit would be a leading-digit system, using middle digits would reverse the focus to the center of the number, and using letters as the primary unit would not be a numeric terminal-digit approach. The defining feature of a terminal-digit system is that the ending digits are the principal organizing unit.
