## Math tag[]

It is written that "However, math tag is officially obsolete, and hence should not be used." Where is the source? 🐟 Fish fish fish ... 🐠 07:08, 10 August 2021 (UTC)

- I don't find description of "officially obsolete" in Fandom help and MediaWiki help and Wikipedia help which uses the same system (Math extension of Mediawiki). If no one shows the source within 2 days, I remove the description because it is a fake information. 🐟 Fish fish fish ... 🐠 09:33, 10 August 2021 (UTC)

- The "official" means the official decision by community members, and hence there is no source in FANDOM's help page. Sorry for the ambiguity. Let us remember what we have experienced with the math tag. First, the mathjax was intended only to be used for complicated expressions, because the mathjax costed more loading time (cf. Forum:MathJax + GoogolBot). As far as I remember, the majority of the users prefered the math tag in old days, because of the loading time. There were several discussions on which to use, but we were using both (cf. Template_talk:No_MathJax).

- However, the biggest accident occurred. The first accident was the destruction of math tag by the system update of FANDOM on 14/07/2018 (cf. User_blog:Cloudy176/Looks_like_the_math_tags_no_longer_work). I note that Googology Wiki:GoogolNews explains that the mathjax is broken, but I think that it is a typo of the math tag. Most people got disappointed, and tried to replace all math tags by the mathjax. The accident was not solved so long (cf. User_blog:Cloudy176/Math_tags:_follow-up), and people tend to ask other users only to use the mathjax. That is why I wrote "official".

- After a while, the math tag was fixed. Then several people tried to replace the mathjax by the math tag again, but replacing the mathjax by the math tag is a sort of persistence of personal preference unless the mathjax has a trouble. So, it sometimes caused edit wars. Also, the math tag sometimes caused troubles, if I remember correctly. So, in order to avoid further edit wars and troubles, I proposed to clarify the officiality of the mathjax (cf. Googology_Wiki_talk:Policy#Proposal_to_create_a_guideline_page), and the admin C7X agreed with it. Since nobody else gave opinions, I created the guideline page and included the description.

- I am sorry, but I do not understand why it is a sort of a fake. (You mean, wrong use of "official"? Or is the consensus outdated?) Since inserting the math tag is also not recommended by members, I think that the revision does not match the intention.

- Then it is ok. I just want to ask one question, anyway.

- > Suppose that you are a developer of Math extension or Mediawiki. If you read the sentence "Math tag is obsolete" what do you think?
- I think nothing more than "math tag is not currently used unlike old days", but I guess that you are trying to telling me something different. Is there a special meaning of "obsolete" in some branch of technologies, e.g. engineering? I do not know any other meaning than "frequently used in old days and currently less used". I made some awful mistake here, right?

- Math tag is so widely used, for example in Wikipedia, so people do not say Math tag is obsolete in normal meaning. So if you write something like "we do not use math tag in Googology Wiki", it might be OK, but "Math tag is obsolete" is a very misleading expression. 🐟 Fish fish fish ... 🐠 16:16, 10 August 2021 (UTC)

- I see. Thank you for the explanation. I propose that you first revise the description, because the current description is unintentionally so misleading (and possibly offensive against developpers according to you) that it can be harmful. And after that, if there is an opinion, then we can discuss the revision. What do you think about it?

- Thank you. After the revision, it is good to discuss whether we allow the math tag to be used. One point is that we can use it because it is supported. The other point is that using two distinct systems increases the future maintainance cost. If we decide whether we allow or not, then it is good to clarify the conclusion in order to avoid troubles between users. (A voting can give an answer, but I am not certain.)

- For blog post, it is clearly allowed. For main space, mathjax is recommended. I wrote "standard method". So we can ask someone to use mathjax if someone is consistently using math tag. Anyway intention is to avoid edit war, and math tag can be replaced with mathjax if someone uses math tag. It is just one time and therefore not an edit war. If it is not replaced, actually it is not a big problem. As you know, people do not read guideline, so even we prohibit math tag people use math tag and we should ask for the user every time for such user. So prohibiting it or not is not a problem. We just write that we recommend mathjax and ask every time. 🐟 Fish fish fish ... 🐠 05:29, 11 August 2021 (UTC)

- I agree. My point is just that it is helpful if we clarify that we are allowed to replace the math tag by mathjax, because currently we are allowed. If we do not clarify it, then some unnecessary trouble might occur, because people might believe that replacing the math tag by mathjax also is thought as an unconstructive edit. (I know that not so many people read the guideline, but they perhaps read it when some trouble occurs. In that case, it is good to have a clear guideline for the situation.)

- Thank you.

- For everyone: based on the discussions above, I am suggesting a revision of guideline as this change. I welcome any suggestions to make it better. 🐟 Fish fish fish ... 🐠 05:21, 11 August 2021 (UTC)

## MathJax is not supported on phones[]

In #How to display a mathematical formula, you say that we need to use MathJax `\(#\)`

, where # denotes the content. However, this doesn't work on phones. For phones, what we're going to do? —Preceding unsigned comment added by SeveralLegend9998 (talk • contribs)

- It doesn't work in previews either. And sometimes it doesn't work at all unless I refresh the page. I don't think we should continue to use MathJax as it's very unreliable in my opinion. Ixfd64 (talk) 17:39, 26 October 2022 (UTC)

- You can use a standard tool in a phone like "display a PC version", cannot you?

- Great.
