Right or wrong
edit- In Finland, it is used as a symbol for a correct response alongside the check mark as an incorrect response.
I do not know about Finland, but about Denmark, I'd say
- In Denmark, e.g. marking homework, it is used as a symbol for an incorrect response, alongside the check mark for correct responses.
Which (as I read it) is pretty much the opposite.--Nø (talk) 11:16, 4 April 2020 (UTC)
- Odd, that contradicts the source I just added! Unless I seriously misread it, could you check please? It's the Unicode consortium discussion list, so arguably not a 100% RS, but we would need a new source. Could you do some research in Danish because the English language sources won't be as reliable. --John Maynard Friedman (talk) 13:11, 4 April 2020 (UTC)
- Check mark disagrees with you too. So maybe you went through school thinking all your wrong answers were right😁 (Your English is so good, I doubt that is true). --John Maynard Friedman (talk) 13:16, 4 April 2020 (UTC)
- Actually, I've been a maths teacher for 20 years - and I never encountered a student who misunderstood check=it checks out, and ⁒=this is wrong. But I guess I didn't have students from Finland (though from many parts of the World).
- Sources. All I have found is this one [1], in Danish, notes that the check that in a computer dialog box and in Danish marking means OK or Correct, in Swedish, Norwegian and Finnish may mean Wrong. In Swedish, R is used for Right, and in Finnish, ⁒. It does not mention that ⁒ is used for Wrong in Danish, but mentions that it is confusing that the Finnish sign for Right looks like a Danish minus (that used to be the obelus, ÷).--Nø (talk) 14:09, 4 April 2020 (UTC)
- I don't think that even Saga Norén could explain how that happened! Feel free to update accordingly, it doesn't matter if the source is not in English. --John Maynard Friedman (talk) 16:51, 4 April 2020 (UTC)
Examples?
editWould it be good to add examples to this article to show how the commercial minus sign is used? For instance, in financial documents, is it used in a similar way that parentheses are used for contra amounts? --MtPenguinMonster (talk) 08:47, 23 October 2023 (UTC)
- Closest readily available is the image at Obelus#In mathematics but that uses a form that looks identical to U+00F7 ÷ DIVISION SIGN.
- Maybe you can find Johann Philipp Schellenberg (1825). Kaufmännische Arithmetik oder allgemeines Rechenbuch für Banquiers, Kaufleute, Manufakturisten, Fabrikanten und deren Zöglinge [Commercial arithmetic or general arithmetic book for bankers, merchants, manufacturers, craftsmen and their pupils] (in German). p. 213. "NB this is not the 1805 version available from Google Books".
- Anybody else? Otherwise it may be that this, like long s, has a code point for historians to use but is no longer seen in the wild? --𝕁𝕄𝔽 (talk) 10:02, 23 October 2023 (UTC)
