Roman numerals

here are seven basic Roman numerals.

|Symbol |Value |

|I |1 (one) (unus) |

|V |5 (five) (quinque) |

|X |10 (ten) (decem) |

|L |50 (fifty) (quinquaginta) |

|C |100 (one hundred) (centum) |

|D |500 (five hundred) (quingenti) |

|M |1000 (one thousand) (mille) |

Multiple symbols may be combined to produce numbers in between these values, subject to certain rules on repetition. In cases where it may be shorter, it is sometimes allowable to place a smaller, subtractive, symbol before a larger value, so that, for example, one may write IV or iv for four, rather than iiii. Again, for the numbers not assigned a specific symbol, the above given symbols are combined:

• II or ii for two

• III or iii for three. The final character is sometimes "j" instead of "i", often in medical prescriptions.

• IV, iv, IIII, or iiii for four

• VI or vi for six

• VII or vii for seven

• VIII or viii for eight

• IX or ix for nine

• XXXII or xxxii for thirty two

For large numbers (4000 and above), a bar is placed above a base numeral to indicate multiplication by 1000:

• V for five thousand

• X for ten thousand

• L for fifty thousand

• C for one hundred thousand

• D for five hundred thousand

• M for one million

For very large numbers, there is no standard format, although sometimes a double bar or underline is used to indicate multiplication by 1,000,000. That means an underlined X (X) is ten million.
