The **Roman numerals** are certain Latin script letters that may be used to represent numbers.

## OverviewEdit

The Roman numerals are a numerical system composed of seven Latin letters. They are, in this order, from lower to higher: **I**, **V**, **X**, **L**, **C**, **D** and **M**.

Each said symbol represents a different number, in this order: one, five, ten, fifty, one hundred, five hundred and one thousand. There is no symbol to represent a null quantity. It is possible to represent numbers different from these, through combinations of letters, such as XIII, MMMMCCV and MCMXCIX. A combination is made of smaller groups of letters, each group in increasing order from right to left. The whole combination represents a number.

When there are two letters together, each of them are worth powers of ten and the second letter is worth ten times the first, the value of this group is equal to the second letter subtracted by the first letter. Therefore, IX represents nine, XC represents ninety and CM represents nine hundred. By extension, XCIX represents ninety nine.

The numerical values of the symbols I, X, C and M are added if written up to three times together. Therefore, The the number III represents three and the number MM represents two thousand.

A macron multiplies the value of a group of letters by one thousand. Therefore, IV represents four thousand.
