For finite sets of integers A1,..., An we study the cardinality of the n-fold sumset A1+...An compared to those of (n-1)-fold sumsets A1...A{i-1}+A{i+1}...+An. We prove a superadditivity and a submultiplicativity property for these quantities. We also examine the case when the addition of elements is restricted to an addition graph between the sets.
