Summary of how to express numbers
Important: Different dialects might have different ways of expressing numbers. These recommendations are based on what is known of the original wordlist.
See Time, Tenses for suggestions on expressing time, including the time of day.
For a list of known cardinal numbers, go to the cog and select only the "number" and "use expanded dictionary" filters at https://mandocreator.com/tools/dictionary/index.html
To express with words numbers greater than 10, write from left to right the word for each number in each place. For hundreds, add the number prefix used with the tens number to olan. For thousands, add the entire tens number to olan. Examples:
eleven: ta'raysh solus
(listed in original dictionary)
thirty-three: ehn'eta ehn
sixty-six: rol'eta resol
(listed in original dictionary)
four hundred six: cur'olan resol
eight thousand nine hundred seventy-eight: shehn’eta’olan shek’olan tad’eta sh’ehn
There is no official way to express numbers greater than 9999. The simplest fan method is to write each number word individually. For example, write 18765 as solus sh'en e'tad resol rayshe'a.
Fan options for writing large cardinal numbers
Write each number out without specifying place, the same as for numbers larger than 9999; example for 9999: she'cu she'cu she'cu she'cu.
Write numbers paired by 10s number; example for 9999: shek'eta she'cu shek'eta she'cu
Write the largest number only as a special term and the others as single digits (this method starts with the largest number to indicate the size of the digit and lists the rest of the numbers as if they were single digits); example for 9999: shek'eta'olan she'cu she'cu she'cu
The words for the hundreds are deduced by fans based on the words for the tens.
100 - olan
200 - ad'olan
300 - ehn'olan
400 - cur'olan
500 - raysh'olan (original), she'olan (fan update)
600 - rol'olan
700 - tad'olan
800 - shehn'olan
900 - shek'olan
1000 - ta'raysh'olan
2000 - ad'eta'olan
3000 - ehn'eta'olan
4000 - cur'eta'olan
5000 - she'eta'olan
6000 - rol'eta'olan
7000 - tad'eta'olan
8000 - shehn'eta'olan
9000 - shek'eta'olan
The simplest way to create ordinal numbers is by adding a descriptor suffix to the end of the last word in a cardinal number. Because "first" is such a common word, it has its own variation, sol'yc.
Examples: Second is expressed as t'adyc. 9999th is expressed as shek’eta’olan shek’olan shek’eta she’cula or as shek’eta she’cu olan shek'eta she'cula.
Various dialects may have different rules for how to create ordinal numbers; follow local guidelines when asked.
A few simple mathematical expressions can be presented using only the base dictionary.
Addition: [number] bal [number] cuyi [sum]. Example: Solus bal solus cuyi t'ad. One and one is two. 1 + 1 = 2
Subtraction (option 1): [number] teh [number] cuyi [difference]. Example: Solus teh solus cuyi naas. One from one is nothing. 1 - 1 = 0
Subtraction (option 2): Te'habi [number] be [number] par [difference]. Example: Te'habi solus be solus par naas. Take one out of one for nothing. 1 - 1 = 0
Multiplication (option 1): [number] de [number] cuyi [product]. Example: Solus de solus cuyi solus. One by one is one. 1 x 1 = 1
(This is inspired by the formula for determining area.)
Multiplication (option 2): [number] ti [number] cuyi [product]. Example: Solus ti solus cuyi solus. One with one is one. 1 x 1 = 1
(This is a shorthand version of expressing a multiplication problem by saying "[number of] groups with [number of] parts each equals a total of [number].")
Division: [number] lo [number] cuyi [quotient]. Example: T'ad lo cuir cuyi t'ad. Two into four is two. 4 / 2 = 2.
Range of numbers: [number] at [number]. Example: Solus at cuir enaabe. One to four meters.
Various dialects may have different rules for how to present mathematical expressions; follow local guidelines when asked.
