Hello again, I read and have applied what it is explained here:

https://orgmode.org/manual/Working-with-LaTeX-math-snippets.html#FOOT136

It works rather well, but for some symbols it does not work : for example for \(\bot\)  the code for falsity constant in  LaTeX, it does not work.

I imagine that I have not installed some library?

Hello,

I would be  glad to get a  configuration for an easy export  from an org
file  to  an  odt file.  My  problem  is  that  this org  file  contains
mathematical  formulae   written  for  LaTeX  export   and  also  tables
(tabular).

I do not know well libreoffice.

Your help is welcome.

Best wishes,
