Fun Fact
The English number naming system follows a base-10 grouping model called the short scale, which differs from systems used in many European countries where "billion" historically meant a million million.
Historical Context
Writing numbers in words dates back to ancient accounting systems in Mesopotamia and Egypt. Formalized number naming conventions emerged with the development of positional numeral systems and were later standardized during the rise of global trade and legal documentation in medieval Europe.
