    abstract     = {In this paper we report about a didactical experience in the field of algebra realized in a first class of secondary school. The topic concerns the use of the ``Ruffini's method'' as a technique for assessing a polynomial (not only for doing the divisions) and the ``discovery'' of its computation efficiency/complexity. During the experience the students have obtained three different ways for expressing the sum of the natural numbers from 1 to n. (orig.)},
