'''{{tp|nasin nanpa pona}}''' is an extension to the {{tp|[[pu]]}} [[counting system]] for large and exact numbers. It was created by {{tok|jan Kapilu}} and {{tok|jan Tepo}} in 2021 and sets out to express big numbers compactly.<ref name="kapilu-tepo">{{cite web|url=https://wyub.github.io/tokipona/nasinnanpapona|title=nasin nanpa pona|lang=tok|website=Wyubsite|author={{tok|jan Kapilu}}, {{tok|jan Tepo}}|archive-url=https://web.archive.org/web/20220203101845/https://wyub.github.io/tokipona/nasinnanpapona|archive-date=2022-02-03|url-status=dead|access-date=2024-02-05}}</ref> It is part of the {{tp|[[su]]}} style for writing the year in dates.<ref name="Oz">{{cite Oz}}</ref>
==Overview==
In Toki Pona, numbers lack any central role. In fact, exact numbers beyond 2 are mostly avoided, only using {{tp|[[mute]]}} in the right [[context]] to say what the quantity is in the given situation. However, not only are exact numbers seemingly more needed sometimes (or at least they seem useful to a degree), some speakers insist on continuing to speak in ways that force the topic of not only exact, but also big numbers. Hence, people have been making and keep making [[nasin nanpa ali ike|new counting systems]] with varying degrees of being in line with [[minimalism]] and [[usefulness]]. Many of these end up replacing the way overly precise counting is already done as documented, for example, in the book {{lipu pu|en}}.
===Introduction in {{tp|pu}}===
The book {{lipu pu|en}} documents the following counting system. Given that {{tp|nasin nanpa pona}} is backwards compatible, all of these examples hold true for it as well.<ref>{{cite pu}}</ref>

===Extension to the counting system===
{{tp|nasin nanpa pona}} allows for one extra step to simplify numbers beyond a couple of hundreds: if numbers smaller than 100 precede {{tp|[[ale]]}}, then {{tp|ale}} gets multiplied by this number. As a result, {{tp|nasin nanpa pona}} is {{w|centesimal}} (base 100). The word {{tp|wan}} also precedes {{tp|ale}} to avoid confusion with the {{tp|pu}} system.<ref name="kapilu-tepo" />

===Writing===
There is no official way to denote the number zero as documented by the creators. However, some users use the letter {{tp|X}}, borrowing the shape from the {{tp|sitelen pona}} glyph for {{tp|[[ala]]}} ({{sp|ala}}).
===Decimal numbers===
Less established is this extension to

==Notable usage==
In the book {{Oz|en}}, {{tok|[[jan Sonja]]}} used {{tp|nasin nanpa pona}} as the date format for the copyright year in {{tp|[[sitelen pona]]}}, also using the then-little-known numeric variant of {{tp|[[mute]]}} ({{sp|mute2}}).
{{Example
|tenpo sike nanpa mute ale mute tu tu
|Year 2024
|tenpo sike nanpa mute2 ale mute2 tu tu
}}
