The rules as we know them today now governing the Roman numeral system had absolutely nothing to do with the ancient Romans whatsoever because they were introduced during the Middle Ages and so the given numbers when converted into Roman numerals are now considered to be MCMXCIX, CXCIX and XIX respectively but the Romans themselves would have most probably calculated them in either of the following formats:-
IMM+ICC+IXX = MMCCXVII => (2000-1)+(200-1)+(20-1) = 2217
MDCCCCLXXXXVIIII+CLXXXXVIIII+XVIIII = MMCCXVII => 1999+199+19 = 2217
The above calculations were quite simple and straightforward to work out but for more complicated calculations the Romans would have used an abacus calculating device.
QED
Cmxcix + xiv + mcmlxxxvii = mmm. It should be all in capital letters, but the system changed them.
Nowadays we would convert 1900 into Roman numerals as MCM but the ancient Romans would have probably worked out the given numbers as follows:-X+CMM+XC = MM => 10+(2000-100)+(100-10) = 2000X+MDCCCC+LXXXX = MM => 10+1900+90 = 2000QED

They are not considered valid. It is a simple algorithm based entirely on the letters in the names. Use different calculators and you will get totally different answers.
The ancient Romans probably worked them out as follows:-MDCCLXVIIS+SIX = MDCCLXXVI => 1767.5+(10-1.5) = 1776MDCCLXVIIS+VIIIS = MDCCLXXVI => 1767.5+8.5 = 1776Note that the rules as we know them to day now governing the Roman numeral system had nothing to do with the ancient Romans because they were introduced during the Middle Ages.QED
There is no such measure as a milometre. Unfortunately the prefix could be kilo or milli which would give two entirely different answers.
They are worked out as in the following formats:- MDCCS:. + LXXV:. = MDCCLXXVI => 1700.75 + 75.25 = 1776 MDCCS:. - LXXV:. = MDCXXVS => 1700.75 - 75.25 = 1625.5
