What Are Roman Numerals?

What are Roman Numerals you ask? Roman Numerals come from ancient Rome. They are a "number system" that uses a combination of letters to express a number!

Although not widely used anymore, Roman Numerals are still used in many places. Roman Numerals are used by sporting events like the Olympic Games, the NFL, and the Super Bowl. Roman Numerals are used for Queens, Kings, and Popes. They are also sometimes used for years, like 2013 is MMXIII. Of course, you also see Roman Numerals on clocks.

 To read or write a Roman Numeral, follow these rules: There are seven capital letters in the Roman Numeral "alphabet" and each letter represents a number as follows: I = 1 V = 5 X = 10 L = 50 C = 100 D = 500 M = 1000 If two or three letters are the same in a row, then simply add them together. Like III = 1 + 1 + 1 = 3 A letter can only be repeated three times. For example, CCC will work, but CCCC is not valid. If two letters are next to each other, compare the first and second letter. If the first letter is larger than the second letter, then add them up together. For example, XV is 10 + 5 = 15 Again, if two letters are next to each other, compare the first and second letter. If the first letter is smaller than the second letter, then subtract the first letter from the second letter. For example, IX is 10 - 1 = 9 A bar on top of a letter makes it 1000 larger. There is no Roman Numeral for zero or a negative number. All Roman Numerals are integers.
