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.
See answer to question: ' How do you add together 1666 and 1999 in two different ways using Roman numerals'
The five letter word MIMIC can be formed from Roman numerals but as the individual numerals are in the wrong order it isn't a real Roman numeral.
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).
If you mean as Roman numerals then MDDL = MML which is the equivalent of 2050
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.
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)
In today's modern usage of Roman numerals, CCCXCIV represents 394, but the ancient Romans would have converted and notated the equivalent of 394 into Roman numerals entirely quite differently.
Hindu/Arabic numbers are the ones used in most countries of the word. they are; 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0. Roman numerals work on an entirely different principal and the numerals most often encountered are; I, V, X, L, C, D and M.
