This is the body of the test question. There isn't actually anything here. I'm curious to see how many downvotes this gets.

Initial usage of \frac:

\frac{1}{2}


$\frac{1}{2}$

• All that malicious content... $\def\text#1{\Huge\color{\red}{\mathrm{I~love~beer!}}}%Hahahaha!$ Feb 6, 2017 at 5:15
• or is it here? $%...$ Feb 6, 2017 at 5:16
• Maybe here ... $\def\text#1{\Huge\color{\red}{\mathrm{I~love~beer!}}}$ Feb 6, 2017 at 5:16
• You can't really tell.... Feb 6, 2017 at 5:17
• You would have to check every comment. $\def\text#1{\Huge\color{\red}{\mathrm{I~love~maths!}}}$ Feb 6, 2017 at 5:17
• And how would the ordinary user know how to look at it in the first place... $\def\text#1{\Huge\color{\green}{\mathrm{I~love~beer!}}}$ Feb 6, 2017 at 5:18
• @Martin-マーチン Use the app, where MathJax in comments doesn't render. :) Feb 6, 2017 at 11:15
• @hBy2Py Downvoted for loving beer. Feb 6, 2017 at 11:16
• What are you talking about?$\def\text#1{\Huge\color{\purple}{\mathrm{I~love~chemistry!}}}$ Feb 6, 2017 at 11:18
• @orthocresol In the app, since the comments are not rendered, there should not be any effect in the answers, too. And you still have to chuck every comment.... O.o Feb 6, 2017 at 11:21
• @Martin-マーチン That was sneaky.......! I just meant, if we are trying to find rogue mathjax, then we can just check the app. $\def\text#1{\Huge\color{\pink}{\mathrm{I~hate~chemistry!}}}$ Feb 6, 2017 at 11:25
• Downvoted for not being provoking enough Feb 6, 2017 at 11:40
• @Martin-マーチン Hahaha, when it re-rendered the question after I edited it, the graffiti showed up there, too. :-) Feb 6, 2017 at 12:49
