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 '17 at 5:15
• or is it here? $%...$ Feb 6 '17 at 5:16
• Maybe here ... $\def\text#1{\Huge\color{\red}{\mathrm{I~love~beer!}}}$ Feb 6 '17 at 5:16
• You can't really tell.... Feb 6 '17 at 5:17
• You would have to check every comment. $\def\text#1{\Huge\color{\red}{\mathrm{I~love~maths!}}}$ Feb 6 '17 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 '17 at 5:18
• @Martin-マーチン Use the app, where MathJax in comments doesn't render. :)

• What are you talking about?$\def\text#1{\Huge\color{\purple}{\mathrm{I~love~chemistry!}}}$ Feb 6 '17 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 '17 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. $\def\text#1{\Huge\color{\pink}{\mathrm{I~hate~chemistry!}}}$
