What were the real and original rules that once governed the Roman numeral system with explanations?
The rules as we know them today now governing the Roman numeral system were introduced during the Middle Ages, presumably to make Roman numerals more compatible and easily converted into Hindu-Arabic numerals that were gradually superceding Roman numerals in Western Europe via Spain at the time, but the original rules once governing the Roman numeral system can be historically determined as follows:-
1 Numerals: M=1000, D=500, C=100, L=50, X=10, V=5, I=1 and S=1/2 or 0.5
2 A zero symbol was not needed because place value of numerals were self evident
3 A numeral or numerals enclosed in brackets indicated multiplication by 1,000
4 As for example (V)=5,000 or (CXXIII)=123,000
5 Whenever possible numerals were abridged using subtractive notation
6 As for example VIIII=IX => 9=10-1
7 As for example MDCCCCLXXXXVIIII=IMM => 1999=2000-1
8 Under todays rules 1999 is now MCMXCIX
9 But as M+CM+XC+IX they will methodically add up to IMM
10 Under todays rules 29 is now XXIX
11 But amongst the ruins of the Colosseum in Rome entrance 29 is XXVIIII
12 Positive and negative numerals went in opposite descending directions
13 As for example CCXXVIIIIS=SXXCCL => 229.5=250-20.5
14 As for example LXXXVIIIIS=SXC => 89.5=100-10.5
15 Even today clues to the real rules can be extracted from the Latin language
16 Clues to the real rules that once governed the ancient Roman numeral system can be found in the book 'History of Mathematics' volume 2 by David Eugene Smith first published in 1925 and ISBN 0486-204-308
