The lower numbers

Letoa counts in base 12. Base 12 is the dominant base on Toa. Some cultures use base 6 and others use base 12 with a sub-base of six but the global auxiliary language has gone with the majority.

Numbers up to a dozen

Here are the numbers in Letoa from 1 to 12. Following Earthly notation conventions, A and B are used here to provide one-place characters for ten and eleven. Our twelve is then written as 10. It may also be called a dozen.

Base 12	Letoa	Base 10
1	Sa	One
2	Seu	Two
3	Enu	Three
4	Bata	Four
5	Õã	Five
6	Ẽĩ	Six
7	Kai	Seven
8	Dane	Eight
9	Lo	Nine
A	Iku	Ten
B	Chasha	Eleven
10	Go	Dozen

The next eleven numbers

The next eleven numbers in Letoa take the numbers above and combine them with the word go.

Base 12	Letoa	Base 10
11	Gosa	Thirteen
12	Goseu	Fourteen
13	Goenu	Fifteen
14	Gobata	Sixteen
15	Gõã	Seventeen
16	Gõẽĩ	Eighteen
17	Gokai	Nineteen
18	Godane	Twenty
19	Golo	Twenty-one
1A	Goiku	Twenty-two
1B	Gochasha	Twenty-three

Counting the dozens

When counting the dozens, the go is placed at the end and the multiplier is prefixed to it. These compounds are all regular.

Base 12	Letoa	Base 10
20	Seugo	Twenty-four
30	Enugo	Thirty-six
40	Batago	Forty-eight
50	Õãgo	Sixty
60	Ẽĩgo	Seventy-two
70	Kaigo	Eighty-four
80	Danego	Ninety-six
90	Logo	One hundred and eight
A0	Ikugo	One hundred and twenty
B0	Chashago	One hundred and thirty-two

Intermediate numbers place the dozen first, then the remainder.

Seugo iku – 2A (two dozen plus ten, i.e. 34 in base 10)

Ẽĩgõã – 65 (six dozen plus five, i.e. 77 in base 10)

Counting the grosses

A dozen dozens form a gross and the word for gross is kou. It may be written as 100 in base 12. This is equivalent to one hundred and forty-four in base 10. Unlike the English word hundred, kou may be compounded. Once again, compounding is entirely regular.

Hokou – 300 (three gross, i.e. 432 in base 10)

Batakou danego sa – 481 (four gross, eight dozen and one, i.e. 673 in base 10)

Kaikou seugo iku – 72A (seven gross, two dozen and ten, i.e. 1,042 in base 10)

Note that one gross is always written as kou alone. It is never written as *Sakou or *Sa kou.

Kou õãgo – 150 (one gross and five dozen, i.e. 204 in base 10)

The most important number?

Finally and perhaps most importantly we should note that Letoa has a word for zero. That word is chumã and it is important as the presence of zero enables positional notation to be used when writing numbers.
