Roman numerals are not appropriate for doing even simple operations such as an addition. Pressumably, the ancient Romans had to use some other system, or perhaps an abacus, to do the actual addition.
You can try using basically the same system you use for Arabic (i.e., our standard) numbers: add the ones and ten places separately; for the ones place in the result, split it up into tens and ones, and add the tens to the other part of the result.
Convert from Roman numerals to Arabic numerals, add, convert back to Roman numerals.
