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.
Nowadays we would convert 999, 14 and 1987 into Roman numerals as CMXCIX, XIV and MCMLXXXVII respectively but notwithstanding the aforementioned inasmuch that there exist compelling evidence to suggest that the ancient Romans would have probably calculated the required calculations as follows:-IM+IXV+VXMMII = MMM => (1000-1)+(15-1)+(2002-15) = 3000DCCCCLXXXXVIIII+XIIII+MDCCCCLXXXVII = MMM => 999+14+1987 = 3000Note that the above calculations are fairly simple and straight forward but for more advanced arithmetic the Romans would have made use of an abacus calculating device.QED

It is not known exactly when the Roman numerals started. They were not started by by anyone in particular. They were the result of several centuries o evolution. It is thought that the Roman numeral system was derived from a tally system where tally marks were carved on wooden tally sticks which was in use in archaic Italy. This system was in use by shepherds in Italy until the 19th century. Thus, it originated from the notches of the tally mark system, which gave 1 as I, 2 as II and 3 as III. Every fifth notch there was the symbol Ʌ for 5, which was a double cut. The tenth notch was cross cut, giving a X. The system was originally complicated and was later simplified. The number 8 which had been IIIIVIII was abbreviated to ɅIII, where Ʌ represented four previous notches. A further abbreviation was to turn four, which had been four tally marks (IIII), into IɅ. Over the centuries with the development of the Latin alphabet the tally marks eventually became identified with the Latin letters I, V and X. Thus the symbol Ʌ was inverted to become V.50 was written in a number of ways N, И, K, Ψ, ⋔ or ᗐ. It had acquired a standard symbol, ⊥ , by the time of Augustus and later it was inverted as it became identified with the letter L. 100 was Ж, ⋉, ⋈, H. The symbols for 50 plus an extra stroke Ж (X superimposed on I) became the main one and was written as >I< or ƆIC. It was later abbreviated as Ɔ or C. C finally became the standard symbol because it was the initial letter of the word centum (hundred). 500 was a Ɔ superimposed on a ⋌or ⊢ -. It became D or Ð by the time of Augustus and finally settled as the letter D. 1000 was an encircled X, Ⓧ. By the time of Augustus the Greek letter phi (Φ) was in use. It changed again to Ψ and ↀ, then to ∞ and then to⋈. Finally it became M, the first letter of the word mille (thousand).
Oh, dude, in the ancient Greek numeral system, they didn't have a symbol for zero like we do now. They were all about counting with letters, not numbers. So, yeah, zero was a big fat no-show in their math party. Like, imagine trying to balance your checkbook back then. Good luck with that!

ii plus xii equals xiv in Roman numerals.
The answer is 281.....but im Roman Numerals it is.......CCLXXXI

MMMI. M=1000 and I=1. Therefore three times M plus one times I equals MMMI.
If you mean CD plus DC then in Roman numerals they add up to M meaning 400 plus 600 = 1000
CXVIII
1400 in Roman numerals
20
IV + I = V
As l11 are not Roman numerals they cannot meaningfully be added to XX (20) to make any result.
XL is equivalent to 40 in Roman numerals, and X represents 10. Thus, XL plus X is 40 + 10, which equals 50. In Roman numerals, 50 is represented by the letter L.
Three plus four is seven. Or in Roman numerals, III plus IIII equals VII. Please know that while the rules say that four should be IV, in actual use the Romans wrote four as IIII as IV were the first two letters of Jupiter's name. (Ivpeter)
