How were Roman numerals used in calculations? A work by Sextus Julius Frontinus in 95 A.D. uses fractions of 288ths to calculate the diameter of water pipes. How could this be done with I, V, C, X, L, D and M?
This book describes the methods used in doing addition and subtraction with these numbers and tells how this was still being done almost a thousand years after the end of the Roman Empire.
