Some distributivity-like results in the medieval arithmetic of Jordanus Nemorarius and Campanus de Novara

The present article explores the treatment of some distributivity-like properties in the works of Jordanus Nemorarius and Campanus de Novara. The perspective afforded by this analysis gives rise to some interesting insights concerning medieval attitudes towards the relationship between geometry and arithmetic, in particular as part of the Euclidean tradition. It also sheds interesting light on medieval conceptions about arithmetic as an autonomous discipline requiring its own proper foundation.
