Betreff : Re: [SIGCIS-Members] History of Rome. How did they calculate?
Well, if we going retro, I theorize it is the following that they used since new thinking in Roman historiography suggests the Romans had contact with Asian markets. Jim

Hi all:
Does anyone know how the Romans calculated with the Roman numeral system?
What is the meaning of the right-most slot of the Roman hand abacus?
Do you have Roman hand abaci (original devices or replicas) in your collection?
Thank you very much for your help.
Best wishes,
Herbert Bruderer
