We estimate some sums of the shape S(Xβ1,…, Xβm): = [sum ]1 [les ] d1 [les ] Xβ1… [sum ]1 [les ] dm [les ] Xβm ƒ(d1,…, dm), when m$\Bbb N$ and f is a nonnegative arithmetical function. We relate them to the behaviour of the associated Dirichlet series

F(s1,…, sm) = [sum ]d1 = 1[sum ]dm = 1 f(d1,…, dm)/d1s1dmsm. The main aim of this work is to develop analytic tools to count the rational points of bounded height on toric varieties.
