Thank you very much for your answer. But I am afraid that there is a
misunderstanding on my problem. What I try to do is to insert mathematical
formulae with mathematical symbols as a text in an Excel cell. An equivalent
is done under word with the embedded software Mathtype which is not,
unfortunately embeddable in Excel.
Have a nice day,

One way to do this is to copy the formula to the clipboard, and paste
it without the "=" to another cell. This converts it to text.
