Hello,
can someone please help me with export to PDF or Word.
When I export to PDF, some of formulas are correct, some of them I can not see properly.
I tried everything, every plugin, but always the same. Even when I am in the reading view modus, those formulas are wrong. see attachment. I am doing something wrong, but I don’t know what.
Also, can I add numer the pages when I export to the PDF?
I would be thankfull

Someone might be able to help you with the formulas if you provide the source for them. And furthermore it’s not unlikely that when you get them correct in the reading view, they’ll also be correct when exported to PDF.
PS! What happens if you remove from your formulas?
Hi, thank you for the answer. What do you mean when you say “source”?
For example this is what I write in the editing view.
$$
V_0=hS_0 – c_0
$$
When I go to the reading view I am getting this yellow thing …nbsp…
That is strange, as I don’t get it. Neither in live preview nor in reading view. Could you please do the Show debug info, to show which version of Obsidian you’re on?
Do you get the same behaviour if you try your formulas in the Sandbox vault?
Using this code block:
$$
\begin{aligned}
V_0&=hS_0 – c_0 \\
V_1^d &= hS_1^u-c_1^d \\
V_1^u &= V_1^d \\
hS_1^u-c_1^u &= hS_1^d-c_1^d
\end{aligned}
$$
I get this in reading view:
And this after Export to PDF:
My test vault is still on version 1.6.4, with Installer 1.5.3, so I might need to update soon it seems… 
But I do get the same appearance when running on 1.7.7, with the 1.7.7 installer.
your code is working in both: reading view and PDF export. this means I have always to write \begin and \end?
in the sandbox valut I am getting the same error with my codes, but your formula works.
what I cann’t understand, why some of my codes are working, but some of them not?

I don’t understang what does “nbsp” mean 
“Non-breaking space”.
You are on an extremely old version of the Obsidian installer. I don’t know if it will help or not, but I highly recommend you download Obsidian from the website, and reinstall manually.
It won’t affect your notes. But there are some things that cannot auto-update in Obsidian. Every once in a while, it’s important to re-download from the website.
What is the origin of your code? Did you copy it from somewhere which might have that non-breaking space? I typed in my version from scratch.
The align is just needed when you want to align (or have) multiple lines. It shouldn’t be needed for a single line formula.
Hi, thank you for the hint.
I installed new version, but it didn’t help.
I delete in the formula “non vreaking formula” and it works, in both, reading view and export PDF.
I think this answered my question. Thank you.
I write all formulas. No copy paste.
But I never thought the empty space between two characters could cause the problem.
Thank you for the hint how to write in the most efficient way.
If you have more such hints, please tell
