Rules for using Roman Numbers
- The letter I is used only before the V and the X, for example: IV = 4; IX = 9.
- The letter X is used only before L and C, for example: XL = 40; XC = 90
- The letter C is used only before the D and the M, for example, CD = 400; CM = 900
- The letters I, X, C and M are only grouped followed three times, for example: III = 3; XXX = 30.
- To represent numbers greater than 4000 use a dash above the letters, which means multiplying the number by one thousand, for example, .
- Equal letters add up the values, for example: II = 2; XX = 20.
- Two different letters with the smallest before the largest subtract their values, for example: IV = 4; IX = 9.
- Two different letters with the largest before the smallest, add up their values, for example: VI = 6; XI = 11.
- If between any two letters there is another smaller one, its value will belong to the letter following it, for example: XIX = 19; LIV = 54.
Curiosity
Invented in ancient Roman times, Roman numerals were created to make counting easier. So the Romans developed a numbering system, with the letters of the alphabet.
The Romans did not know the representation of zero and, for this reason, this numbering system does not have any letter to represent it.
