In todays modern usage of Roman numerals: MCDXCIX = 1499
But the ancient Romans would have probably wrote it out simply as IMD = (1500-1)
In today's modern notation of Roman numerals it is now 1499 = MCDXCIX but the ancient Romans would have worked it out on an abacus calculating board as MCCCCLXXXXVIIII and then probably abridged it to IMD in written format which means 1500-1 = 1499
In today's modern notation MCDXCIX are Roman numerals that represent 1499 (1000+400+90+9 = 1499) But the Romans themselves would have probably calculated 1499 on an abacus counting device as MCCCCLXXXXVIIII and by adding I to the right hand side and subtracting I from the left hand side of these numerals simply wrote it out as IMD (-1+1500 = 1499) Today's rules governing the Roman numeral system were introduced during the Middle Ages and that was centuries after the decline of the Roman Empire.
