I noticed you removed the math tags from the Munchausen task. Why? Were they not rendering correctly? [[User:Fwend|Fwend]] ([[User talk:Fwend|talk]]) 12:15, 24 September 2016 (UTC)
: Yes, They rendered the text invisible on Internet explorer. :-( What good are they anyway? --[[User:Walterpachl|Walterpachl]] ([[User talk:Walterpachl|talk]]) 13:15, 24 September 2016 (UTC)
::: What good are they? They render formulas much better. [[User:Fwend|Fwend]] ([[User talk:Fwend|talk]]) 14:17, 24 September 2016 (UTC)
:: The MediaWiki processing of <math> tags can go wrong if they enclose unexpected redundant space. As a result, ill-formed HTML is generated which prevents the display of the graphic file for the formula on most browsers, though a minority, like Firefox, can still use an alternative route, if the right fonts are installed, by locally processing MathML.
:: On the whole, you should find that you don't need to entirely remove the <math> tag - eliminating redundant space between the tags, particularly just after the opening tag, and just before the closing tag, should usually be enough, though there are some other special space patterns which also choke the MediaWiki's translation of <math> tags into HTML [[User:Hout|Hout]] ([[User talk:Hout|talk]]) 13:27, 24 September 2016 (UTC)

::: For a list of tasks descriptions with formulae which have accidentally been made invisible to most browsers by <math> tag editing in the last six months, see:

:::: I know about the redundant space but mine didn't have any, as far as I can see: <nowiki><math>3435 = 3^3+4^4+3^3+5^5</math></nowiki>. I just tried it with Edge and it does indeed not render, which is strange because Edge does render the Wikipedia math tags.
