How do I paste a formula from LibreOffice-Math to LibreOffice-Impress

I use Math to create formulae and would like to add the formulae to an Impress presentation. How do I do this and maintain the background of the slides?

If the Math module is still open: Edit > Select all > copy. Then in Impress Insert > Object > Formula, and there Edit > Paste.

If you have saved your formula and the Math module is not open, then you can use Insert > Object > OLE > Create from File > Search.

Math-Formulas are actual embedded OLE-objects. That was done, because this concept allows to have only one rendering engine for formulas.
