      @nairalos do it by induction. order the edges of the parallelogram and rotate it so the first one lies on the x-axis, second in the xy-plane

          @nairalos of the diagonal entries. but that IS the determinant when the matrix is triangular.

          @nairalos Yeah you will need to walk it through to understand it but I think this is the most compact 'intuitive' way to see it.

          @nairalos so you're doing induction on the formula volume = base x height. heights are the diagonal entries, volumes are sub-determinants
