Elementary math in tp

Post by jan Nowo »

tu en tu lon tu tu.
tu weka wan lon wan.
tu mute tu lon tu tu.

I am perplexed as to division and integration, derivation are perhaps out of scope for the language.

As for basic new geometry shapes:

linja wan tu = triangle
linja pona tu tu = square
linja pona lili tu tu = rectangle, parallelogram
linja luka = pentagon

Sure.y not 'lon'; maybe 'li sama' or maybe just 'li'.
'mute' means 'increase", 'lili' means "decrease" so natural for addition and subtraction. multiplication is harder, but 'kipsi' might work for division.
figures are more than just lines , possibly 'lipu' for plane figures and thn information about lines.
Given the deficiencies of tp numbers, this seems premature -- but fun.

I think "li" is neccessary. Maybe "li lon".
wan en tu li tu wan.
tu en tu li tu tu.

I express negative numbers so:
tu weka wan li wan.
wan weka tu li ala weka wan.
ala weka wan = -1

I dubt how to express multiplication:
A. tu wan tenpo tu li luka wan.
B. tenpo tu wan la tu li luka wan.

I use "tenpo" as "x times y" in English.

musi taso sona ala. 'tenpo' as "instance, occasion" sort of works for "times", despite the obvious English influence (how does it go in other languages?), 'weka' in the "take away" sense ditto. 'en' for "plus" is iffier. But I do think that 'li' is enough, without 'lon'. Still, given only two numbers (or three or four, depending on how you count) this seems pretty premature.

Here is my idea:

Addition: mute, mute nanpa e xyz
Multiplication: sin, sin nanpa e xyz tenpo
Subtraction: lili, lili nanpa e xyz
Division: kipisi nanpa e xyz tenpo, or for fractions abc sewi xzy.

Alas, more opaque than the number system before. Go step by step and component by component, explaining each.
