Hi, All:
Let V be a finitedimensional space, which can be decomposed as: V=Z(+)W . How can we express the dual of V in terms of the duals of Z, W? I think this has to see with tensor products, but I'm kind of rusty here. Any ideas, please?

The dual of the direct sum is the direct sum of the duals.
