... (x1 + y1 , x2 + y2 , x3 + y3 ) ; geometrically, the points 0 , x , x + y and y are successive vertices of a parellelogram in the plane determined by the three points 0 , x and y. (As is well-known, this gives a way to determine the resultant of two forces.) The above algebraic operations allow us to ...

... and scalar multiplication are defined exactly as for the direct product, so that the external direct sum coincides with the direct product when the index set I is finite. The R-module M is the internal direct sum of the submodules Mi if each x ∈ M can be expressed uniquely as xi1 + · · · + xin where 0 ...
