Comments on: How to Convert Roman Numerals

on 9/12/2007 I just purchased a Roman numeral ring from ebay and on it is the numerals XIIIX then a space and then XIIIX
in a circle just wondering what this means. My guess would be 10+3-10=3? or is it =6,or =3,=3? Is there any meaning to this ring, or is it just a look. Any help on this would be greatly appreciated. Thanks Mark

on 3/23/2006 Usually, while using Roman Numerals, people forget the fact that placing any smaller value in front of any larger value, indicates subtraction. For example, people might write 'IX' for the number '11' when it is in fact a '9'.

on 2/4/2008 You can never put more than 3 in a row, but you can however put more than 3 in the roman numeral its self

on 11/22/2005 Never repeat the same letter more than three times. For example, XXXX is not the way to represent 40. XL would be forty. The exception to this rule is M. You can write as many M's as you wish.

Another trick is to write a bar over top of the Roman numeral. That indicates to multiply by 1,000. For example, if a bar were placed over the Roman numeral V, that would represent 5,000.
