Numerus is a basic standard 4 function calculator... that operates in Roman numerals.
Numerus is often used for teaching purposes, especially in the USA. Here is a link to a lesson I especially liked:
Exploring Roman Numerals (thanks to Tony Vincent - Omaha, Nebraska).
Numerus Source Code
I have ported
Numerus in different languages and development tools, that was a very good exercise for me in all these tools.
Numerus is even a sample software for all these tools. So, the
Numerus source code is open and free.
