Subject: Re: Roman Contribution to Math

The Romans were indeed very good mathematicians. However, they tended

to study only what is now called "applied math." They wanted to be

able to use their knowledge to build the wonderful roads and bridges

you mentioned.

The Roman calculations were done on a board with grooves and holes.

I've tried to draw the board below, and indicate the place values each

groove and hole had.

On this board, they would place pebbles, "calculi" in Latin. This

brings us to one of the Roman contributions to math: the words

"calculate", and "calculus" both come from this origin. They would

place one pebble in the appropriate place for each letter in their

numeral. Other pebbles could be added to them representing another

addend. The pebbles would have to be rearranged so no more than 4

were in a groove, or no more than 1 in a hole. They manipulated the

pebbles to do all their calculations.
