Under today's rules governing the Roman numeral system 499 is considered to be CDXCIX which makes it almost impossible for any kind of numerical interaction with other numerals.
But the Romans themselves in the past would have calculated the equivalent of 499 as CCCCLXXXXVIIII which can be methodically contracted to ID (500-1)
499 in Roman numerals: CDICToday it is written out as: CDXCIXBut during the Roman era it was most probably wrote as: ID (-1+500 = 499)
Nowadays 499 in Roman numerals is now considered to be CDXCIX but the ancient Romans would have simply worked it out as ID meaning 500-1 = 499
The Roman numeral representation of 499 is CDXCIX, which can be broken down as follows: CD (400) + XC (90) + IX (9).

Notwithstanding today's notation of Roman numerals the numbers of 19, 49, 99 and 499 would have probably been notated as IXX, IL, IC and ID respectively during the Roman era which makes addition straightforward as follows:- IXX+IL = IILXX (68) IILXX+IC = CLXVII (167) CLXVII+ID = DCLXVI (666) When writing out Roman numerals use the least amount of numerals whenever possible
