768-457: The system could handle larger numbers, did not require a separate reckoning tool, and allowed the user to check their work without repeating the entire procedure. Late medieval Italian merchants did not stop using Roman numerals or other reckoning tools: instead, Arabic numerals were adopted for use in addition to their preexisting methods. By the late 14th century, only a few texts using Arabic numerals appeared outside of Italy. This suggests that
800-516: The terms digits , numbers and numerals often implies only these symbols, although that can only be inferred from context.
