I would like to insert, as comment, as explanations, as title ...,
mathematical formulae under Excel
To insert, one after the other, symbols retrieved from character tables is
very harsh.
Is there a scientific editing software embedded in Excel (Mathtype is only
embedded in Word) ?
Alternatively, is there an ergonomic solution (easy updating, not impacting
the memory size of the file ...) for this problem ?

Thank you very much for your help,
