# MathJax

• Continuing the discussion from Do this maths. It R Hard.:

A while back, MathJax was requested on here, but since it's not that active, I'm a bit loath to just install it on here without at least some smoke-testing elsewhere, since I'm not sure how widespread it is on other instances.

I've installed it on my test instance, if anyone wants to play with it:

Just toying with this at the moment - no idea if it's in any fit state to put on here yet:

Just like the real thing!

• Cynic...

• I remember asking about it a while back, because I wanted some math symbols one time in one post. After using Discourse for a while, I find I don't really need math symbols to say what I want to say on here.

Also, do we really want to add this to the Markdown/BBCode/HTML disaster we already have?

Filed Under: That's my $0.02, you can keep the change • Also, do we really want to add this to the Markdown/BBCode/HTML disaster we already have? • Is that the Robocop 3 solution? Overload the system so it crashes? • ....... right. need to make sure that the "don't be skynet" rule gets overwritten in the crash. • I thought that was Robocop 2. Robocop 3 was the one with the jet pack and the robot ninjas and basically it was fried ass. • Also, do we really want to add this to the Markdown/BBCode/HTML disaster we already have? Sure. The more syntaxes we can fit in there, the merrier! • MathJax + RoboCop = Robot Jox • I thought that was Robocop 2. You could be right, because I'm pretty sure Weller was in it, and he wasn't in 3. I haven't seen either of them in a long time so I was going from memory. • \newcommand{\P}{\mathbf{P}\left[#1\right]} Anyway, it's trivial. Hanna samples without replacement. Letting$O_i$be the event that Hannah's$i\$-th sample is orange, we have

\begin{align*}
\P(O_1 O_2) &= \frac{1}{3} \
&= \frac{6}{n}\frac{5}{n-1} \
30 &= \frac{1}{3} n(n-1) \
90 &= n^2 - n \
0 &= n^2 - n - 90
\end{align*}

I got my pencil and paper out for this?

• What version of mathjax is this using? I've never heard of the "aligned" environment, and it's rejecting align*

Nevermind, wrong discourse.
