Re: Numbers and math

I will answer for Chleweyish
tal asked:

> A classic question is: how do you count to ten in your conlang?
rey, raw, rawet, rap, rapor, raper, rapsot, rur, ruryam, ruryor.

Ordinal is a verb, formed adding verb suffix (-i in infinitive, -e in
indicative) to the cardinal...
Well, not that simple: "first" is not derived from any cardinal and
the n-th cardinal use n-1 cardinal as root:
  2nd: reye
  3rd: rawe
  4th: rawete
    etc.
For short hand you write the number followed with -i/-e (superscribed
if you want).
  2nd = 1e
  3rd = 2e
  4th = 4e

yes: _ba_.

yes.

Instead of percentils, fractions of one are used.  The way to express
fractions with a power of two as denominator follows the way of
integers.  There are ways of expressing rational numbers with other
denominators and for translating base-ten percentiles.

>  - how do you add, subtract, multiply and divide? (if you know how)
If you have practice with base 2 it wouln'd be any problem: just write
the numbers in base two and opperate.  I will think of an apropiate
way to write numbers down without using decimal digits, probably a
generalization of the numeric system of Thompinian (based on EISH5:
look at http://www.geocities.com/Paris/Rue/9028/conlang/ for more
info).  When I decide for it I will try to figure out how operations
can be performed with this notation.

About grammar... it isn't  decided yet.

Grammar undecided yet.
