Compute the free energy of transfer

Question: Compute the free energy of transfer involved in the hypothetical transfer of electrons from complex 1 to complex 4. The electron reduction potential of complex 1 in -0.32V. Complex 2 is +0.03V. Complex 3 is +0.04V. Complex 4 is +0.23V.
HINT: Think about the aIDitive nature of free energies to approach this problem.
