IX = 9 IXX = 19 IX times IXX = -I(-I+XX)+X(-I+XX) Removing brackets = +I-XX-X+CC Collecting like terms = -XXX+CC+I When simplified = CLXXI (171) Please note: Remember that in maths a minus number multiplied by a minus number becomes a positive number. Thus -I times -I = I David Gambell, Merseyside, England.

In accordance with the rules governing the Roman numeral system introduced during the Middle Ages and centuries after the fall of the Roman Empire the above Hindu-Arabic numerals converted into Roman numerals are XVIII, XIX, XIV and XLIX respectively which are a confused mishmash of numerals making them almost impossible to work out any mathematical operations with them. But evidence from ancient manuscripts and indeed the Latin language itself suggest that the Romans themselves would have most probably wrote out these numerals as IIX, IXX, IXV and IL then tallied them up in the following logical manner:- IIX+IXX = XXXVII XXXVII+IXV = LI LI+IL = C Hindu-Arabic conversion:- 18+19 = 37 37+14 = 51 51+49 = 100 For more complicated calculations the ingenious Romans would use an abacus counting device.
