For the equation deltaG= -nFE, why can’t you add up the E’s of both half reaction to get Ecell?

Ecell should be E(cathode/reduced) - E(anode/oxidation). If the negatives worked out that way, there should be scenarios in which you could add the potentials of the half reactions to find the total potential

In the overall reaction the electrons in the cathode and anode half reactions cancel out.
