USAGE HISTORY

• In general, Roman numerals can be converted
  mathematically by simply assigning a numerical
  value to each letter, and adding them left to
  right in order of decreasing value to get the
  total
• the total is then calculated by adding the
  numerical values of all the letters in the
  sequence. For example, MDCLXVI 1000 500 100
  50 10 5 1 1666.

• A well-known, but still often confusing feature
  of modern Roman numerals is the subtraction
  principle, which requires that a lower numeral
  appearing before a higher one be subtracted from
  the higher value, not added to the total. For
  example, XIX represents the number 19 (X IX, or
  10 9) rather than 21, which is written as XXI
  (10 10 1). Likewise the Roman numeral for the
  year 1995 is usually written as MCMXCV (M CM
  XC V, or 1000 900 90 5).

• Another present-day convention is the avoidance
  of more than three consecutive occurrences of the
  same letter in favor of the more succinct forms
  achieved by using the subtraction principle --
  for example, IV for IIII (4), XL for XXXX (40),
  and CD for CCCC (400). An exception is the
  numeral M, or 1000, which is used 4 times to
  represent our number 4000, since the Romans had
  no single-letter numeral representing a higher
  value than M. It is now also customary not to
  repeat the values V, L, or D (5, 50, or 500) in
  the same numeral.
