Hi :)
It probably doesn't get quite so far into it but the official Math Guide is ready
http://wiki.documentfoundation.org/Documentation/Publications#LibreOffice_Math_Guide
The docs team have done an amazing amount in the last couple of weeks.
Regards from
Tom :)

Hi Marc,

Now you are in the formula editor. And then Tools> Import Formula.
Only if yo don't exit the equation editor before selecting
Tools->Import, which one might do in as much as the documentation does
not include those few precious words "while the equation editor is
open", lol.
Now, as far as importing xml files, I have never been successful at
importing mathml and must assume that this is accomplished through some
secret handshake as well ;-)
for example, an attempt to import test.xml which consisted of the following:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE math PUBLIC "-//W3C//DTD MathML 2.0//EN"
"http://www.w3.org/Math/DTD/mathml2/mathml2.dtd";>
<math xmlns="http://www.w3.org/1998/Math/MathML";>
<mrow>
<mi>a</mi>
<mo>⁢<!--⁢ --></mo>
<msup>
<mi>x</mi>
<mn>2</mn>
</msup>
<mo>+</mo>
<mi>b</mi>
<mo>⁢<!--⁢ --></mo>
<mi>x</mi>
<mo>+</mo>
<mi>c</mi>
</mrow>
</math>
was unsuccessful.
I had tested that very same example before I had answered. Besides the fact, that the character
⁢ is rendered wrong, the import is without problems.
So there must be some difference between my and your way. So next try with a step by step
description:
Precondition: The MathML is saved as file on disk, for example "mymath.xml".
1. Open a Writer document or use a new one. Set the cursor where the formula should be.
2. Insert > Object > Formula. Now the equation editor is open. The top menu has changed, a part of
the writer document is shown, with a rectangle where the formula will be, and a command window with
a blinking cursor exists.
4. Tools > Import Formula. You get a file picker. Choose your MathMl-file, here mymath.xml. Click
on button 'Insert'.
5. Now you have the proper command in the command window. If something is wrong (for example the
character ⁢ mentioned above), you can correct it.
6. Klick outside the formula into your Writer document. Finished.
An attempt to export similar code as writer xml was similarly
ineffective on import.
If you only want to convert a single formula to MathML and your formula is inside a Writer
document, then right-click the formula. The context menu opens and the last item is "Save as...".
Use this and select "MathML" from the list of available file formats. You will get a single MathML
file. It does not matter whether you use the file extension .mml or .xml.
Reimporting this file as described above, gives the same formula as exported, because the original
LO formula is written to an annotation element and read when imported.
You should use grouping brackets to generate a well structured formula in LO, although LO does not
need them to render the formula. It will give better results in export.
If you want to export the whole Writer document with an easy access to the MathML without
unzipping, you can use File > Export > type XHTML, or File > Save as > type "Flat XML".
Do you understand German? Than the German "Handbuch für Math" on
http://de.libreoffice.org/hilfe-kontakt/handbuecher/ might give you some ideas.
Kind regards
Regina
