In today's notation of Roman numerals the above numbers converted into Roman numerals are XIX, XLIX, CDXLIV, XCIX and CCCLXXXIX respectively. To perform any kind of arithmetical operations to these numerals is almost impossible.
However, notwithstanding the aforementioned the Romans probably worked out 19, 49, 444, 99 and 389 as IXX, IL, IVLD, IC and IXCD respectively in subtractive notation because:-
IXX is a simplification of XVIIII (-1+20=19)
IL is a simplification of XXXXVIIII (-1+50=49
IVLD is a simplification of CCCCXXXXIIII (-56+500+444)
IC is a simplification of LXXXXVIIII (-1+100=99)
IXCD is a simplification of CCCLXXXVIIII (-111+500=389)
Simplification is obtained by placing equal values to both sides of the numerals but in opposite directions and then tallied up in the following manner:-
IXX+IL = IILXX (19+49=68)
IILXX+IVLD = DXII (68+444=512)
DXII+IC = DCXI (512+99=611)
DCXI+IXCD = DD = M (611+389=1000)
In his reference book about ancient numeracy systems entitled "History of Mathematics" volume 2 by David Eugene Smith first published in 1925 and ISBN 0486 204 308 he gives examples of how the Romans would sometimes simplify their numerals in the above manner.
Today's rules governing the Roman numeral system were introduced during the Middle Ages but that was nearly a thousand years later when there were no longer any Romans around. Presumably the rules were made so that Roman numerals could be easily converted into Hindu-Arabic numerals that were gradually being introduced into Western Europe.

How do you work out 1776 plus 1999 in Roman numerals giving reasons for your answer?
Today we write out 1999 in Roman numerals as MCMXCIX because of changes made to the rules governing the Roman numeral system during the Middle Ages and to add these numerals to MDCCLXXVI is almost impossible. But the Romans themselves would have calculated 1999 on an abacus counting device as MDCCCCLXXXXVIIII and probably simplified them to IMM by placing I to both sides of the numerals. So: MDCCLXXVI + (-I+MM) = MMMDCCLXXV (3775)

What are the possible differences of 99 from 1999 in roman numerals giving details of your work?
In today's terms 1999 and 99 in Roman numerals are MCMXCIX and XCIX respectively. MCMXCIX - XCIX = MCM (1000-100+1000 = 1900) Alternatively in the days of the Roman Empire the Romans themselves would have probably wrote out 1999 and 99 as IMM and IC respectively. IMM - IC = CMM (-100+2000 = 1900)
