  The following table displays how Roman numerals are usually written in modern times:
  
  The numerals for 4 (IV) and 9 (IX) are written using subtractive notation, where the smaller symbol (I) is subtracted from the larger one (V, or X), thus avoiding the clumsier IIII and VIIII. Subtractive notation is also used for 40 (XL), 90 (XC), 400 (CD) and 900 (CM). These are the only subtractive forms in standard use.
  
  A number containing two or more decimal digits is built by appending the Roman numeral equivalent for each, from highest to lowest, as in the following examples:
  
  Any missing place (represented by a zero in the place-value equivalent) is omitted, as in Latin (and English) speech:
  
  The largest number that can be represented in this manner is 3,999 (MMMCMXCIX), but this is sufficient for the values for which Roman numerals are commonly used today, such as year numbers:
  
  For larger numbers (4,000 and larger): Both before and after the introduction of Arabic numerals in the West, from ancient times through medieval and modern, users of Roman numerals have used various means to write larger numbers.
