Roman numeral numbers in different languages?

Answer 1

Roman Numerals are themselves foreign. As their name implies, they are Roman. Therefore, the language in which Roman Numerals originated was Latin. Although adopted throughout the Anglo-sphere, they retain their Romanesque properties and functionality. Therefore, if Roman Numerals have been inserted into another language, they are still Roman Numerals. In short, a RomanNumeral is still a Roman Numeral regardless of who uses it.

In a broader sense, tally based number systems, or more accurately, a Unary Numeral System, is used by most cultures in some form. For example, the character æ­£ (Han) is used in China, Japan, and Korea. It starts out as one line, and lines are added until all five lines that form the character are in place. A specific ordering of which lines go where and when exists in this system.

Other cultures have additional, equally unique methods of rudimentary counting. For further information, search UnaryNumeral System on Wikipedia.
