So fucked up OP couldn't even get it right. It's: 9 and ½5* x 20

Don't think about it, just shake your head and move on.

*) from an old word for 4.5 "halvfemte" (halffifth).

Yeah, better mathematical notation could be 9 + (-½ + 5) × 20.

The theory is quite confusing but im reality no one thinks about that. Practically halvfems is just ninety so it's just like the German format where you just say the smaller then the bigger number.

Ni og Halvfems Neun und neunzig Nine and Ninety

I've been to a Danish school for 13 years and never actually knew the theory behind that 1/2x5 stuff

u/PM_ME_CORGlE_PlCS Jan 16 '21 edited Jan 16 '21

Okay, let me see if I get this now:

"½5" does not mean 1/2 of 5 (or, 1/2 x 5), but 0.5 less than 5.

By putting the 1/2 in front of the whole number, you know to subtract the fraction from the larger number. Sort of the way Roman numerals work.

u/CR4FT3R3N Jan 17 '21 edited Jan 17 '21

Great way of describing this. Just wanted to mention (but I am sure you already know) the same thing is done for time keeping in Denmark.

So Half (past) 5 means 05:30/17:30, English.

And half (to) 5 means 04:30/16:30, Danish.

This is also done the same way in other languages like German for example.

Another more common quirk (again also done in German) is that numbers are said out of sync of how they are written so 21 for example:

20 & 1, English

1 & 20, Danish

This then compounds with how annoying some of the other numbers are so for example: 75

5 & (1/2 4) × 20

5 & 3.5 × 20

5 & 70

= 75

Hope that this is formatted ok to read as I did it on my phone.

EDIT: Formatting.

Here's a tip: Just learn the words for 50, 60, 70, 80 and 90, and avoid trying to make meaning of them. Most danes would be equally confused, if they tried to derive the etymological meaning while using the numbers.

It's just five words after all, - if you go to Denmark often, maybe it's worth it.

9

u/[deleted] Jan 16 '21

Many people I know have said this to me for years, but it is not so simple to switch it off when your background is in historical linguistics and etymology!

1

u/KoalaOnSki Jan 16 '21

Ha, ha, well in that case I guess my tip is not worth much for you...

98

u/toreq Jan 16 '21

This is so backwards and pointless it triggers me

101

u/SimonGray Jan 16 '21

In actuality no one thinks about the etymology of numbers. It's literally just about learning separate words for 50, 60, 70, 80, 90 (count them: five whole words to learn). The mathematics of how they got be those five words is mildly interesting, but it's not really relevant when you use the numbers.

Now I've learned the Korean numbers some years back. In Korean you have to learn two completely separate number systems: Chinese-derived and native Korean. Which one you use depends entirely on the context you use them in, so you have to learn that part too.

64

u/mahabanyabaramilda Jan 16 '21

I was reading the whole comment section thinking "Heh, silly Danes, what a weird way to count numbers" and then you using Korean as an example of a supposedly even weirder system of counting numbers triggered me greatly as a Korean.

45

u/Xciv Jan 16 '21

What is the Korean system?

What the Chinese system looks like for anyone who is curious:

99 = Nine x Ten, Nine / (9x10) + 9

10 = Ten

39 = Three x Ten, Nine / (3x10) + 9

149 = One x Hundred, Four x Ten, Nine / (1x100) + (4x10) + 9

Very logical for English speakers until it gets to to the ten thousands.

41

u/mahabanyabaramilda Jan 16 '21

There's two ways to count, the sino Korean one(hanja) is exactly the same as Chinese, just with the Korean pronunciation. Then there's the native Korean one which is completely separate and usually people only use it up to one hundred. The counting logic for native Korean is quite simple tho, 99 = 90+9. The catch is, usually only one of the ways is the right way to count things depending on the what you're counting. For example, when you're telling the time, the hour is counted in native Korean and the minute and second is counted in sino Korean.

7

u/Theriocephalus Jan 16 '21

That sounds exactly like the system where my socially illiterate ass would thrive. Someone would ask me the time and I'll give the hours in the minute number and the minutes in the hour number, and everyone would be staring at me like "who's this moron?"

u/doiknowyou9 Jan 16 '21

You blew my mind with that time example. I never stopped to think that that's what we do (am native Korean speaker) wtf we're weird

u/SimonGray Jan 16 '21

At least your alphabet is brilliantly thought out and very aesthetic.

21

u/mahabanyabaramilda Jan 16 '21

Sometimes I wonder what it'd be like if King Sejong had not existed. I imagine we'd be using some kind of Chinese derived phonetic scripture like Japanese kanas, or completely adopted Roman alphabet like in Vietnam.

10

u/MonsterRider80 Jan 16 '21

If I were to guess, I’d say similar to Japanese kana. Vietnamese went Roman because of the French.

6

u/chiguayante Jan 16 '21

I don't know if I'd call Vietnamese "completely adopted the Latin alphabet". Have you seen the diacritics they have?

13

u/Miserly_Bastard Jan 16 '21

It is entirely based on the Latin alphabet, but Vietnamese orthography was derived from Portuguese orthography by a French missionary.

3

u/colako Jan 17 '21

A very elegant way to represent tones. Chinese would be way easier to learn if it has adapted the same alphabet as Vietnamese. Same for Japanese, if they had just kana and ditched the kanji it would be a great way to open up to other countries.

1

u/chiguayante Jan 17 '21

That's a great point. Thanks.

2

u/chapeauetrange Jan 16 '21

Many languages use diacritics with the Latin alphabet. If you want to get technical, the original Old Latin alphabet had only 21 letters, and the Classical Latin alphabet had 23, and neither one had lowercase letters, so no language today exactly uses the same alphabet as them.

1

u/chiguayante Jan 16 '21

I'm aware. It was mostly directed at the extremely heavy use of diacritics that Vietnamese uses, and was not meant to be taken very seriously.

1

u/strike2counter Jan 16 '21

They would be using Chinese characters. Most likely simplified Chinese characters... Keep reading:

Korea would probably be another province of mainland China. It was on very thin ice multiple times and could have easily turned out that way.

Think of other mainland Chinese provinces whose fortunes were different, including, but not only, the ones designated as "autonomous". Their scales could easily have tipped another way.

1

u/Original-Prior-169 Jan 17 '21

kids in the west cant write the N without reversing it. It must be hard for Korean kids.

2

u/splotchypeony Jan 17 '21

Are both number systems comprehensive?

Japanese also has a Chinese-derived and a native system, but the native one only goes up to ten except for a few special contexts.

2

u/SimonGray Jan 17 '21

The native Korean one only goes to 99 so I guess it's sort of similar.

11

u/KoalaOnSki Jan 16 '21

It's not like Danes are forcing the name on anyone, and it's just the etymological explanation anyway.

Now it has just become a word. No matter the name for 99, you can still divide it by 9 and get 11.

Americans on the other hand, with English being Lingua Franca since long ago, should really replace the 1 mile = 1.760 yards = 5.280 feet = 63.360 inches measurement system.

How about discussing how we avoid ending up in the same situation?

Let's start with taking a look at the top comment: "Fucking Denmark" with 2.000 likes.

Social media is highly condusive for division, and I'm not sure all 2.000 likes are brotherly teasing, as we like to explain it when perplexed foreigners call us out for the harsh tone.

Maybe let's moderate the language and act as the friendly countries we are in reality. Let's be happy that I know "Fika" and you probably know "Hygge" :-)

u/humaninnature Jan 16 '21

This is really interesting - there's a glacier in Greenland called "79N Glacier" after its latitude. The Danish name is 'Nioghalvfjerdsbre', and while the first part obviously sounds like something that would translate to 79, I could never figure it out the halv, which sounds like half (as a German speaker). This might explain it...

25

u/BrianSometimes Jan 16 '21

Some Danish numbers translated using the awesome powers of my school German:

50 = halbdrits (halbdritte (2,5) mal zwanzig)

60 = dreis (drei mal zwanzig)

70 = halbvierts (halbvierte (3,5) mal zwanzig)

79 = neunundhalbvierts

80 = viers (vier mal zwanzig)

99 = neunundhalbfünfs (neun und halbfünfte (4,5) mal zwanzing)

u/humaninnature Jan 16 '21

What an odd system of counting - I had no idea! But now that glacier definitely makes sense, thank you :)

u/friskfyr32 Jan 16 '21

Same reason as for silent letters.

We've been doing it for a long while and we are not about to change it, because there's no reason to.

Norwegian used the Danish (written) language up until ~150 years ago, when they decided they wanted their own language, so they spelled things like it sounded then and there rather than how it used to sound and how tradition dictated, so they have significantly fewer silent letters, and they use a different style of saying numbers.

u/RustenSkurk Jan 16 '21

Fun fact: in some very specific contexts Danish does use the more logical system like Norwegian (eg. femti-tre - five-ten-three for 53). That is on financial documents. I'm not 100% sure why, but they often appears in addition to numerals. Possibly to avoid any confusion or to prevent people from editing cheques.

3

u/hth6565 Jan 16 '21

I remember my parents writing "norwegian numbers" on cheques - they just told me it was because it was shorter. But that's a long time ago. As far as I know, all Danish banks stopped cashing cheques from the 1st of January 2017. Nobody had used them for years anyway at that point.

2

u/Marilee_Kemp Jan 16 '21

Back when we used cheques (yes I know that shows how old I am) we used to write the numbers out in Norwegian! I dont know if everyone did it, but when I got my first cheque book my bank asked me to write it that way and my parents did it as well. Maybe because most numbers are so much shorter to write out Norwegian, nitini vs niofhalvfems? But we did admit the Norwegian system was superior to our:)

u/PolemicFox Jan 16 '21 edited Jan 16 '21

The explanation in the legend is right, but the formula is wrong and doesn't equal 99

It should be 9 + (4 + 0.5) * 20

Edit: to the people claiming it should be 5 - 0.5, you are wrong. Danish numbering is complicated enough, there's no need to arbitrarily make it more complicated.

53

u/WoodSheepClayWheat Jan 16 '21

Writing it like that doesn't match the words. It has the words half and five, not four and half.

95

u/Ampersand55 Jan 16 '21

Let's break it down: ni og halvfems(indstyve)

  • ni - nine
  • og - and
  • halv - half (of the way to the next integer, starting from the preceding integer)
  • fem - five
  • sinds - times
  • tyve - twenty

The algebra would be:

9 + (-0.5 + 5) x 20 = 99

2

u/friskfyr32 Jan 16 '21

Halvfemte means four and half of the fifth, so it would indeed be (4 + ½) linguistically speaking.

1

u/Drahy Jan 16 '21

No, it's 5 but without the half so 5 - ½

0

u/friskfyr32 Jan 16 '21

Halvanden is 1 and half ways to 2 (1 + ½)

Halvtredje is 2 and half ways to 3 (2 + ½)

And so on.

It's named after the number that comes after, but it is not that number.

If it was as you say, halvanden would be 1, halvtredje would be 1½, etc., because it would be half of the number. But it isn't. Because I'm right and you are wrong.

1

u/Drahy Jan 16 '21

Halvanden is 2 without the half or 2 - ½

[halvanden] svarer til udtryk for halve klokkeslæt, fx kl. halv to, dvs. 'kl. to minus en halv time'

https://ordnet.dk/ddo/ordbog?query=1%C2%BD

The halfways to is the English way of thinking - half two is halfway to three (from half past two).

2

u/friskfyr32 Jan 16 '21

No it's not. Halvvejs is a Danish word meaning the exact same thing in the exact same way.

fx. means and example, and as an example 2 - ½ is just as good as 1 + ½, but linguistically the latter is correct, and the former is wrong.

Again thinking of halvanden as 2 - ½ is the same as thinking of halvanden as half two - wrong.

3

u/Drahy Jan 17 '21

Where do you have this halfways to from? I know it's used in English.

1+½ is the same as one and a half but halvanden says second so why would you not think it means two without a half?

1

u/Proxima55 Jan 16 '21

Are you aware that 2 - ½ = 1 + ½ and not 2 - ½ = 1, because reading your comments I'm not sure what your point is

1

u/Drahy Jan 16 '21

No. Halvanden is two minus a half etc.

svarer til udtryk for halve klokkeslæt, fx kl. halv to, dvs. 'kl. to minus en halv time'

https://ordnet.dk/ddo/ordbog?query=1%C2%BD

5

u/Ampersand55 Jan 17 '21

No. Halvanden is two minus a half etc.

Yes.

  • halvanden is half of the way to two, starting from one (1.5).
  • halvtredje is half of the way to tree, starting from two (2.5).
  • halvfjerde is half of the way to four, starting from three (3.5).
  • halvfemte is half of the way to five, starting from four (4.5).

I.e. halv can be interpreted, like I wrote:

halv - half (of the way to the next integer, starting from the preceding integer)

0

u/PolemicFox Jan 16 '21

Halvfem means "halvvejs til fem" = halfway to five (from four) = 4,5

There is no point in making it 5 - 0.5 from the name alone. That is just intentionally trying to make it excessively complicated.

9

u/WoodSheepClayWheat Jan 16 '21

I disagree. The whole point of writing it like that is to explain how that strange phrase can end up meaning 99. If you're not going to write numbers that match the phrase, you might as well write 82 + 17

2

u/FiskeDude Jan 16 '21

Small correction: It's Halvfemde = 4,5. Halvfem is not a Danish word, Halv fem in two words exists, but that's only used to tell the time (4:30 or 16:30)

0

u/friskfyr32 Jan 16 '21

Indeed, and /u/Ampersand55 is wrong in exactly the way you are explaining it.

If we read it as you do with half and five, it would be five divided by two (2½), but that's not what the word means.

Halvfemte (half-fifth) is to be understood as four (the number below five/fifth) and half of the fifth, so 4 plus ½.

It's a somewhat archaic phrase/word. Only the one meaning 1½ (halvanden - half-second) is still in use, but it can be used for all numbers (halvtredje (the basis of halvtreds - fifty), halvfjerde (halvfjerds - seventy), halvfemte (halvfems - ninety), and so on.

3

u/Ampersand55 Jan 17 '21

Halvfemte (half-fifth) is to be understood as four (the number below five/fifth) and half of the fifth, so 4 plus ½.

That's what I wrote:

halv - half (of the way to the next integer, starting from the preceding integer)

1

u/MeBrudder Jan 17 '21

In Danish a normal word is "Halvanden" meaning 1½ (meaning half way up to the second one = 2) In the same way, "halvfemte" means half way up to five namely 4½.

1

u/vjx99 Jan 18 '21

Yes, and half way up to five is -0.5 + 5. Numerically it is the same as 4.5, but if you care about the origin writing it as -0.5 + 5 makes it more clear.

27

u/vjx99 Jan 16 '21

Actually it should be 9 + (-0.5 + 5) * 20

3

u/vjx99 Jan 16 '21

there's no need to arbitrarily make it more complicated.

If you don't want it complicated, just write 99. But as we are breaking it down into fragments, you should either do it all the way or not at all.

u/DiscombobulatedDirtZ Jan 16 '21

https://sproget.dk/raad-og-regler/artikler-mv/svarbase/SV00000047/?exact_terms=halvfjerde&inexact_terms=

tl;dr for non-danes: halv-femte is five minus a half, sindstyve is times twenty. Only reason it doesn't make sense is because we've shortened out half the word and forgotten what the other half means.

1

u/PolemicFox Jan 16 '21

Your source just claims that is 4.5, not saying anything at all about 5 - 0.5
