I’m writing a document, where formulas from Math are very important. I had success copy/pasting a couple of times (although it’s really tedious), but now nothing works.

In my document, I do the following:

1: “Insert” > “Object” > “Formula”

2: A Math window opens. I open the file with the formula.

3: “Edit” > “Select All” > “Copy”

4: Back to the Writer window. “Edit” > “Paste”

And then… nothing.

Perhaps my way of doing this is wrong, then please educate me. It was the only intuitive way that I found.

I need help here. The only other option I see is screenshot and copy as .png.

EDIT (22.01.2021, 22:14): Thank You for your answers/comments. I see that I stated my question imprecisely.

The situation is, that I’ve created some quite complex formulas in Math, each formula saved as a single .odf file. I want to integrate these formulas in my Writer document.

In the meantime, I’ve managed to get this to work:

Writer: Insert - Object - Formula

Math opens.

File - Recent Documents, open the relevant file (the normal File - Open is greyed out!)

A new instance of Math opens.

Copy from the lower screen of Math

Paste into the Writer document.

Formula is now there.

There must be an easier way, but I don’t see it. Or I’m too dumb.
