The way we write out Roman numerals today differs in many respects to how the ancient Romans actually did themselves inasmuch that today we would convert 1488 and 1999 into Roman numerals as MCDLXXXVIII and MCMXCIX respectively thus inhibiting any mathematical interaction between them.
But there is evidence to suggest that the Romans would have probably subtracted the equivalent of the given numbers in either of the following formats:-
IMM-IIXMD = DXI => (2000-1)-(1500-12) = 511
Alternatively by cancelling out the numerals:-
MDCCCCLXXXXVIIII-MCCCCLXXXVIII = DXI => 1999-1488 = 511
Note: 5*I=V, 2*V=X, 5*X=L, 2*L=C, 5*C=D and 2*D=M
Values: M=1000, D=500, C=100, L=50, X=10, V=5 and I=1

See answer to question: ' How do you add together 1666 and 1999 in two different ways using Roman numerals'
Throughout the Roman Empire
Hindu Arabic Numerals use numbers but Roman numerals use symbols.
Arabic numerals are called that because the European interpretation of those numbers comes from the Arabs. The numerals are called Arabic numerals (even though they do not resemble modern Arabic numerals in the slightest) to distinguish them from Roman numerals.
MMMDVIII are the Roman numerals for 3528.Improved Answer:The above answer represents 3508 in Roman numerals whereas 3528 is actually MMMDXXVIII in Roman numerals.

VII-XXXI-MCMXCII Note that the way we write out 1992 today is probably different in the way that the Romans actually did themselves.
Hindu-Arabic numerals are: 0 1 2 3 4 5 6 7 8 and 9 Roman numerals are: I V X L C D and M

They are actually called Hindu-Arabic numerals, so named because the system originated in India and was brought to Europe by the Western Arabs.
Roman numerals were actually created by the Etruscans and the city of Rome dates back to about 753 BC
Etruscan numerals. The Etruscans who once ruled the Romans first conceived the idea of representing numerals for different numerical quantities.
