# Is there something wrong with math rendering?

## Recommended Posts

Posted (edited)

In my recent post on the "Geometry of the real number line" thread here,

I wrote the markup for (1 - x)/2 as \frac{1-x}{2}

It rendered correctly when I committed the post. A few minutes later as I was checking for typos, I noticed that it had rendered as "1 - x2". So I edited my post, deleted the apparently faulty markup, and re-entered the correct markup.

It looked fine when I committed my post. This morning as I was checking my mentions, I noticed that it had reverted to "1 - x2" again.

Is this a known issue with the \frac command? Why did the markup render correctly for a while then revert to being rendered incorrectly?

When I RMB on your math (on desktop), I see no MathJax popup menu..

Did you use [ math ] or [ latex ] open & close tags?

I use,

$$\frac{1-x}{2}$$

for inline maths, and,

$\frac{1-x}{2}$

for display maths. It always look fine:

The first expression, $$\frac{1-x}{2}$$, looks as you can see on this line. While the second expression looks like this:

$\frac{1-x}{2}$

It does funny things like those you describe if I click some other website functions or refresh the page before committing my comment.

Make sure everything is plain text. It sounds like you may have some rich text in there.

Thanks all. Must have been just one of those things.
