I don’t know about the Romans but the late Claude Shannon decided to create a Roman numeral calculator (part of our collections - see https://webmuseum.mit.edu/detail.php?term=Throbac&module=objects&type=keyword&x=0&y=0&kv=75603&record=0&module=objects) he called THRoBAC for Thrifty Roman numeral BAckwards-looking Computer.

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.
