Because of changes made to the configuration of Roman numerals in the Middle Ages nowadays we would express 19 in Roman numerals as XIX but the ancient Romans would have probably expressed the equivalent of 19 as XVIIII or as IXX thus facilitating addition in either of the following formats-
1: MDCCLXXVI+XVIIII = MDCCLXXXXV => 1776+19 = 1795
2: MDCCLXXVI+IXX = MDCCLXXXXV => 1776+(20-1) = 1795
Note that in todays configuration of Roman numerals 1776+19 = MDCCXCV
The Latin words for XVIIII and IXX are 'novemdecim' and 'undeviginti' respectively but there is no Latin word for the equivalent of XIX.
QED
See answer to question: ' How do you add together 1666 and 1999 in two different ways using Roman numerals'
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.
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).
The wrong way and the right way which is as follows:- IX+IXX = XXVIII => (10-1)+(20-1) = 28 XXVIII+IMM = MMXXVII => 28+(2000-1) = 2027
CIVIC
Arabic numerals are called that because the European interpretation of those numbers comes from the Arabs. The numerals are called Arabic numerals (even though they do not resemble modern Arabic numerals in the slightest) to distinguish them from Roman numerals.
MIM + MMXIV = MMMXIII or MMCXCIX + MMXIII = MMMXIII There is only one way to write the solution (3013)
before we show how to subtract in roman numerals, let's check the answer first. 1999 - 444 = 1555 1999 = MCMXCIX 444 = CDXLIV 1555 = MDLV if we separate them into each digit: 1999 = M/CM/XC/IX 444 = 0/CD/XL/IV (0 is just there as a placeholder so each has 4 "digits") 1555 = M/D/L/V And after this, we realize why people stopped using roman numerals and went with the superior hindu-arabic numerals. It just works.
VII-XXXI-MCMXCII Note that the way we write out 1992 today is probably different in the way that the Romans actually did themselves.
MMMDVIII are the Roman numerals for 3528.Improved Answer:The above answer represents 3508 in Roman numerals whereas 3528 is actually MMMDXXVIII in Roman numerals.
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.
