The Roman numerals are certain Latin script letters that may be used to represent numbers.
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, MMMCCV 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.
A macron multiplies the value of a group of letters by one thousand. Therefore, IV represents four thousand.
The Arabic numerals are widely known and widely used in many languages, including English.
Roman numerals are essentially known as uppercase letters: I, V, X, L, C, D and M. However, it is possible to use lowercase letters: i, v, x, l, c, d and m. Lowercase Roman numerals are often seen as page numbers for materials prefatory to the beginning of the main body of a work.
There are additional characters from Unicode, specifically designated as Roman numerals. Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, Ⅵ, Ⅶ, Ⅷ, Ⅹ, Ⅺ, ⅺ, Ⅼ, Ⅽ, Ⅾ, Ⅿ, ⅰ, ⅱ, ⅲ, ⅳ, ⅴ, ⅵ, ⅶ, ⅷ, ⅸ, ⅹ, Ⅻ, ⅻ, ⅼ, ⅽ, ⅾ and ⅿ, ↀ, ↁ, ↂ, Ↄ, ↄ, ↅ, ↆ, ↇ, ↈ.
