Dear Nick, Jos� Maria and Paulo (in order of appearance),
Thanks a lot for your contributions to the "Produttoria-Running Product-
Produt�rio Affair".
It seems quite funny how an efficient language such maths can show some
debateworthy differences in labelling the same procedure.
Thanks a lot again.
Kind Regards,
Carlo

Oggetto: Re: st: How to perform a productory
For the sake of completeness:
Two Brazilian diccionaires for the Portuguese language registry the word
"somat�rio". In statistics and mathematics we use the simbol upper-case
Greek sigma. The same diccionaires do not registry "produt�rio", but we use
it in the spoken language and the symbol is the upper-case Geek pi. Then,
curiously, we have the symbol to write, the word to speak but not formally
the writen word.
�bra�os,
Jos� Maria
