# The Roman numerals

As I promise, I will make a special topic

*about Roman numerals*.

## What are Roman numerals

**Roman numerals** are the numeric system of ancient Rome. It uses combinations of letters from the Latin alphabet to signify values. For instance numbers from 1 to 10 can be expressed in Roman numerals as follows:

**I, II, III, IV, V, VI, VII, VIII, IX, X**.

The Roman numeral system is decimal, but not directly positional and does not include a zero (0).

## Roman numeral

**Roman numeral** is any of the symbols used in a system of numerical notation based on the ancient Roman system. The symbols are I, V, X, L, C, D, and M, standing, respectively, for 1, 5, 10, 50, 100, 500, and 1,000 in the Hindu-Arabic numeral system. A symbol placed after another of equal or greater value adds its value—e.g., II = 2 and LX = 60. A symbol placed before one of greater value subtracts its value—e.g., IV = 4, XL = 40, and CD = 400.
