Here is a chart with the numbers 1 through 10 in Roman Numerals, as well as an explanation of how to derive them:

Number | Roman Numeral |
Explanation |
---|---|---|

1 | I |
This is I. |

2 | II |
1+1=2, so we put together two I's to make II. |

3 | III |
1+1+1=3, so we put together three I's to make III. |

4 | IV |
Although 1+1+1+1=4, writing four I's in a row would be a bit tedious. Romans came up with a shorthand for when they would have to write four of the same numeral in a row. Instead of writing IIII, they write IV. Putting a smaller numeral before a larger numeral means you subtract it from that numeral! So you can think of IV as representing 5-1=4. |

5 | V |
This is V. |

6 | VI |
5+1=6, so we put together a V and an I to make VI. |

7 | VII |
5+1+1=7, so we put together a V and two I's to make VII. |

8 | VIII |
5+1+1+1=8, so we put together a V and three I's to make VIII. |

9 | IX |
Although 5+1+1+1+1=9, using the same type of construction we used for writing the number 4, we'll use to write the number 10. Since there would be four I's in a row to write 9 the normal way, we'll use the shorthand way and write IX, as 10-1=9. |

10 | X |
This is X. |
