The rules as we now know them today governing the Roman numeral system had absolutely nothing to do with the ancient Romans because they were introduced during the Middle Ages presumably to make Roman numerals more compatible with Hindu-Arabic numerals that were gradually replacing Roman numerals at the time but there once were only two basic rules governing the Roman numeral system and they were as follows:-
Positive numerals went from left to right in descending order.
Negative numerals went from right to left in ascending order.
As for example: SXCL = -1/2-10+100+50 = 139.5
Note that: -10 is less than -1/2 and that 100 is greater than 50
As for example: SXXCL = -1/2-20+100+50 = 129.5
Note that: -20 is less than -1/2 and that 100 is greater than 50
The above examples were extracted with slight modifications from the reference book 'History of Mathematics' volume 2 by David Eugene Smith first published in 1925 and ISBN 0486 204 308

What is the history about Roman numerals?
In brief, this system of numeracy had nothing to do with the Romans because the system was conceived by the mysterious Etruscans who once ruled the Romans. After the Romans gained their independence from the Etruscans they kept this system of numeracy which became later known as Roman numerals. The way we write out Roman numerals today differs in many respects to how the Romans actually did themselves. The real rules governing the Roman numeracy system were changed in the Middle Ages presumably to make Roman numerals more compatible with Hindu-Arabic numerals that were being introduced into Western Europe at the time.
