Numbers in Seuna

In Seuna the number system uses base 8. Remember that all the numbers in this section are in octal.

Zero

Seuna has a symbol for zero (actually similar to our "o" but a bit smaller). It is called nyegatuna (gap symbol).

From 1 to 7

@aba	@iga	@oda	@ela	@uca	@aisa	@auka
one	two	three	four	five	six	seven

Seuna doesn't have separate symbols for the numbers 0 to 7, but instead uses letter symbols. Also a vertical slash is included. Every Seuna number must have a vertical slash. Unlike words which are written next to other words with no spaces in between, a number must be separated by spaces on either side.

There are 6 words that are derived from the above basic numbers. They are used when there is some uncertainty. For example @igoda could be translated as "two or three" or as "a few", @ucaisa could be translated as "five or six" or as "a few".

From 10 to 77

108	@abau
208	@igau
308	@odau
408	@elau
508	@ucau
608	@aisau
708	@aukau

As with the basic numbers, the above numbers can be combined. @igaudau = "twenty or thirty". There is another form for the above numbers that specifies a range. For example @odaua specifies the range 30₈ to 37₈

Every number from 1 to 63 has its own unique word which can be worked out from the above tables. For example ;-

@igauda

@igauda

@igauda

From 100 to 777

1008	@abai
2008	@igai
3008	@odai
4008	@elai
5008	@ucai
6008	@aisai
7008	@aukai

As with the other numbers, the above numbers can be combined. For example @elaicai = "four or five hundred".

The above set of numbers can also be modified to specify a range. For example @elaia specifies the range 400₈ to 477₈

As with the two digit numbers, every three digit number(i.e. 1 to 777) has its own unique word which can be worked out from the above tables. For example ;-

@ucaiba = 501₈

By the way there is another equally valid way to write 501. It is shown below.

From 512 to 8³⁰-1

To express numbers greater than 511, Seuna has a number of exponention terms. These never occur by themselves but must be proceded by one of the numbers 1 to 511. These exponential terms are each written using a single symbol normally used for a consonant. They are in some ways equivalent to the S.I. prefixes kilo, Mega, giga etc..

83	m	mu
86	y	yu
89	j	ju
812	f	fu
815	p	pu
818	t	tu
821	w	wu
824	n	nu
827	h	hu

So for example;-

34y4 ce (pronounced : @odaula yu @elace) is about^* the population of the UK in 2008. Seuna has a special symbol (pronounced as "ce") which tells us the number is not exact, it is only accurate to three significant figures.

Usually we only deal with approximate numbers. However in some scientific situation you have long and accurately known numbers. For example 34y472m531 (pronounced : @odaula yu @elaikauga mu @ucaidauba). In these situations the letters divide the numbers up into sets of three ... a bit similar to how we use comma's to make long numbers easier to read.

^* If by some chance, the population of the UK was known to be exactly this number, then it would be represented by 34y4̴- (pronounced : @odaula yu @elatiki)

From 1 to 8^-30-1

Of course there is also a way of representing numbers smaller than one, as well. The table below shows the symbols used for this.

8-3	m	mi
8-6	y	yi
8-9	j	ji
8-12	f	fi
8-15	p	pi
8-18	t	ti
8-21	w	wi
8-24	n	ni
8-27	h	hi

Now you can see the same letter is being used to write exponent values greater than one and also less than one. What is to stop confusion between the two sets ? Well for longish numbers with two or more exponent values, the relative order of the exponents should tell you if we are dealing with a greater than one situation, or a less than one situation. For example 34y4̴72m531 must be greater than one, and 34m4̴72y531 must be less than one. However how do we distinguish between numbers that have only one exponent ? Well in these cases we would put a decimal point to the left of the numbers that are smaller than one. The decimal point symbol is a near-vertical dash(represented here by "/"). For example /34y4̴⁓ is a number smaller than one.

Note;- The numbers get there magnitude value from the letter and not the decimal point. Only if there is no letter, do they take there magnitude value from the decimal point. For example /34 would equal (3*8^-1)+(4*8^-2). Whereas /34y would equal (3*8^-5)+(4*8^-6).

And even bigger numbers

The two sets of exponent terms given above can be expanded somewhat to specify a bigger range of numbers. A symbol pronounced mua (written as the Seuna symbol for "m" with a small slash under it) representing 8³⁰ comes after the symbol pronounced hu. Other large exponents are generated in a similar manner up to a symbol pronounced hua representing 8⁵⁴.

And we can expand these terms even more. A symbol pronounced muan (written as the Seuna symbol for "m" with two small slashes under it) representing 8⁵⁷ comes after the symbol pronounced hua. Other large exponents are generated in a similar manner up to a symbol pronounced huan representing 8⁸¹.

In a similar manner the small exponents can be expanded to 8^-81. This is pronounced hian and written the same as huan.

Numbers outside the above ranges are not specified.

Fractions

a unit	haban
a half	higan
a third	hodan
a fourth	helan
a fifth	hucan
a sixth	haisan
a seventh	haukan

Ordinal numbers

Ordinal numbers are adjectives so come after the word that they qualify.

@oda dwolo = three houses

dwolo @odas = the third house

Nouns from numbers

klolo = wheel, klolaga = bicycle ?? kloli = vehicle ??

Negatives numbers

A negative is represented by putting "back/backwards" after the number.

Imaginary numbers

An imaginary number is represented by putting "side/sideways" or "rightside" or "leftside" after the number.

Mathematical operations

Addition

Western mathematical notation	Which is pronounced
2 + 3 = 5	two and three is five
Seuna mathematical notation	Which is pronounced
2,3>5	aga ada ro aca

Subtraction

For subtraction, or addition which inviolves negative numbers, each number must be followed by either "forward" or "backward" depending upon whether the number is possitive or negative.

Multiplication

There is a particle je which is placed between words to be multiplied.

Western mathematical notation	Which is pronounced
2 x 3 = 5	two times three is five
Seuna mathematical notation	Which is pronounced
2+3>5	aga je ada ro aca

Division

15 divided by 5 is 3 ............. 15 shared 3ji is 5

tonda means "to add" or "addition", and jemba means "to multiply" or "multiplication". ??? tondua = subtraction, jembua = division ???
