XII is written by combining these symbols in a specific order, as follows: X + I + I = 10 + 1 + 1 = 12. Sometimes conversion of Roman Numerals can be a daunting task, especially for larger numbers. You can always use a Roman numerals converter if you need to quickly convert Roman numerals to decimal numbers .

## Composing XII in Roman Numerals

To compose XII in Roman numerals, it is necessary to understand the key principles for writing Roman numerals. In general, a smaller letter precedes a larger letter, and the letters are combined to represent a larger number. In the case of XII, I precedes X, which means that I (1) is subtracted from X (10), resulting in 10 - 1 - 1 = 8. The symbol I is then added to 8 to obtain XII.

Roman Numeral | Value |
---|---|

I | 1 |

V | 5 |

X | 10 |

L | 50 |

C | 100 |

D | 500 |

M | 1000 |

## Key Principles for Writing Roman Numerals

Understanding the key principles for writing Roman numerals is essential for composing and understanding them. Here are some key principles to keep in mind:

- When a larger letter precedes a smaller letter, the letters are added together. For example, LX (60) is written as L + X = 50 + 10.
- When a smaller letter precedes a larger letter, the letters are subtracted. For example, XC (90) is written as C - X = 100 - 10.
- A letter is repeated up to three times to represent the sum of that letter's value. For example, III (3) represents 1 + 1 + 1.
- A letter should not be repeated more than three times in succession. For example, IV (4) is written as V - I, not IIII.
