The ancient Romans would have probably added together the equivalent of 1776 and 1799 simply as in either of the following formats:
A: MDCCLXXVI+IMDCCC = MMMDLXXV => 1776+(1800-1) = 3575
B: MDCCLXXVI+MDCCLXXXXVIIII = MMMDLXXV => 1776+1799 = 3575
Note that the modern way of expressing 1799 in Roman numerals is now MDCCXCIX because of changes made to the rules governing the Roman numeral system intoduced during the Middle Ages.
QED
See answer to question: ' How do you add together 1666 and 1999 in two different ways using Roman numerals'
Throughout the Roman Empire
Roman numerals are entirely inappropriate for doing such calculations. I believe the people in Roman times did such calculations on an abacus or something similar - which is basically similar to converting them to the Arabic numbers we use. If you really want to do it in Roman numerals - which is basically NOT a good idea - you would have to keep the thousands, hundreds, etc. separate, and handle carry (for addition) and borrowing (for subtraction).
CIVIC
Bear in mind that Roman numerals actually are numbers, they are just not the kind of numbers that we presently use, which are called Arabic numerals. Arabic numerals were first used in Europe in the year 976 AD. Roman numerals still have not entirely fallen out of use, although for most purposes we use Arabic numerals.

If you mean as Roman numerals then MDDL = MML which is the equivalent of 2050

89.5 minus 8.5 yields a result of 81 . The method or character set I used is completely irrelevant. If you work the same problem more than once and get more than one result, then at least one of them is wrong, and there is a significant probability that both of them are.
CCXV-CCLXXXVIII-(VII)CCCLXXIIII are the above numbers in Roman numerals as the Romans themselves would have probably calculated them.
MIM + MMXIV = MMMXIII or MMCXCIX + MMXIII = MMMXIII There is only one way to write the solution (3013)
A 5-letter word made up entirely of Roman numerals is "VIIII," which represents the number 9 in Roman numerals. In Roman numerals, "V" represents 5, and "I" represents 1. When "I" is placed after "V," it represents 4 (5-1=4), and when "I" is placed before "V," it represents 4 (5+1=6).
