Ok for this example lets take the number 19 XIX and add it to 21 XXI. All you have to do is put them together and combine all like numbers for example here we have XXXIXI. Now to simplify your numbers we know that M = 1000, D = 500, C = 100, L = 50, X = 10, V = 5, I = 1. So we know that this number that adds up to 40 can be written in its simplest form as XL.
Here is another: DCXIII + DCCLXXVII (613+777) = 1390
Combine like numbers DDCCCLXXXVIIIII, now simplify. DD (1000) can be written as M, CCC (300) can be left as CCC, and LXXXVIIIII can be simplified to LXXXVV, and then to LXXXX, and then some more to LXL, and finally to XC (90). Now combine your results and you end up with MCCCXC which is 1390.

How would you add up the four numbers of 49 119 199 and 1409 when converted into Roman numerals?
I would convert them back into Hindu-Arabic numerals, do the addition and then convert the answer to Roman numerals.
How would you add up 1444 and 555 in Roman numerals?
With great difficulty because 1444 in Roman numerals in today's terms are MCDXLIV and to add them to DLV (555) is an almost impossible task. But the Romans probably calculated the above numbers on a abacus calculating board as:- MCCCCXXXXIIII + DLV = MDCCCCLXXXXVIIII = IMM (-1+2000=1999) when simplified. The rules governing today's Roman numeral system were not the same rules in which the Romans themselves actually used because they were changed in the Middle Ages presumably to make it easier to convert Roman numerals into Hindu-Arabic numerals that were gradually being introduced into Western Europe.
