    I'm having problems knowing how and where to start writing a proof. Are there tricks to the trade? For example, what proof would you write for the question below and why?
    Thanks in advance.


    Let V be the direct sum of the R-modules V1, Vn, and let W be the direct sum of
    R-modules W1, Wm. Indicate how a module homomorphism from V to W can be
    represented by a matrix. (The entries of the matrix need not be elements of R.)
