| has gloss | fra: En mathématiques, la somme vide est le résultat dune addition daucun nombre. Sa valeur numérique est par convention égale à zéro. Ce fait est particulièrement utile en mathématiques et en particulier en algèbre. Un cas simple et bien connu est 0.a = 0. La multiplication dune nombre quelconque a par zéro donne toujours comme résultat zéro, parce que nous avons ajouté zéro copie de a, cest-à-dire rien. |

| has gloss | ita: In matematica si usa lespressione somma vuota quando in una addizione non ci sono addendi. Una tale situazione capita ad esempio quando lindice inferiore di una sommatoria è più grande dellindice superiore, come in :\sum_i=2}^1 f(i). In questo caso infatti non cè alcun indice i che soddisfi la condizione richiesta (essere contemporaneamente minore di 1 e maggiore di 2), dunque non ci sono addendi da poter sommare. |
