      International audience ; In his arithmetic treatise, Bézout teaches arithmetic as grounded on quantities and units. It is from this perspective that we consider a property of a "mixed product", involving a multiplication on sets of quantities. In this note, we present the main lines of some didactical research on the use of this property with students of years 7 and 8 (12-14 years old). We focus mainly on the conception of units and related notions, as the multiplicative relation between units of the same kind.
