Given the Sum product....where the number of sums is variable and nested...example....which I write logically rather then Mathematically, easier for me and I think for understanding.... Given... Sum[ k1=1 to q] Sum[k2=k1 to q] Sum[k3=k2 to q] (k1*k2*k3) is there a way to write this as ...Product[Sum] ? I tried Product[a=1 to 3] Sum[k_subscript_a = k_subscript_(a-1) to q] but this didnt work...no nesting What I want is to be able to vary a = 1 to n..... any ideas? thanks....jerry blimbaum
