Inuit, like other Eskimo languages (and Celtic and Mayan languages as well), uses a vigesimal counting system. Inuit counting has sub-bases at 5, 10, and 15. Arabic numerals were not adequate to represent the base-20 system, so students from Kaktovik, Alaska, came up with the **Kaktovik Inupiaq numerals**,^{[1]} which has since gained wide use among Alaskan Iñupiaq, and is slowly gaining ground in other countries where dialects of the Inuit language are spoken.^{[1]}

The numeral system has helped to revive counting in Inuit, which had been falling into disuse among Inuit speakers due to the prevalence of the base-10 system in schools.

The picture below shows the numerals 1–19 and then 0. Twenty is written with a one and a zero, forty with a two and a zero, and four hundred with a one and two zeros.

The corresponding spoken forms are:

0 | 1 | 2 | 3 | 4 |

atausiq | malġuk | piŋasut | sisamat | |

5 | 6 | 7 | 8 | 9 |

tallimat | itchaksrat | tallimat malġuk | tallimat piŋasut | quliŋuġutaiḷaq |

10 | 11 | 12 | 13 | 14 |

qulit | qulit atausiq | qulit malġuk | qulit piŋasut | akimiaġutaiḷaq |

15 | 16 | 17 | 18 | 19 |

akimiaq | akimiaq atausiq | akimiaq malġuk | akimiaq piŋasut | iñuiññaŋŋutaiḷaq |

20 | ||||

iñuiññaq |

(19 is formed by subtraction from *iñuiññaq* 20, just as 9 is formed by subtraction from 10. See Inupiat language.)

In Greenlandic Inuit language:

1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |

Ataaseq | Marluk | Pingasut | Sisamat | Tallimat | Arfinillit | Arfineq-marluk | Arfineq-pingasut |

9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 |
