# Numbering

Dragons often have only four fingers (thumbs is too small), so they use a base eight system for counting. The rest of the planet quickly adopted this octal system.

## Number

When dragons on Dracca trade, they use a octal system.

Figure | Name | Symbol |
---|---|---|

0 | Oct | |

1 | Un | |

2 | Dek | |

3 | Terr | |

4 | Quat | |

5 | Quint | |

6 | Swek | |

7 | Sept |

## Numbers

To write octal numbers, group the figures by four, and put a space between each group. To read the number, simply read each figure of each group. Add a"o" to the end of the last figure of every group, except the last group. Put a "o" at the end of the last figure of the last group.

### Writing octal with decimal figures

You can write octal numbers using decimal numbers (0, 1, 2… 7), but you should always keep
the figures grouping. Group the decimal figures in sets of four, and prepend "0" to the first group.
If the first group already has four decimal digits, then put a group of "0" before.
For instance, don't write ~~17~~ for *unsepti*, and write 0017 instead.
To write the decimal number `1000`, that is `1750` in octal, prepend it
with a group of zeros, so you write `0000 1750` for "one thousand".
