Now, we basically look these guys up on our table for reduction half reactions on the statement conditions and we find that our reduction cell voltage is zero point 43 negative, while our oxidation half reaction is negative zero point 44. Well, actually our reduction going this way because only reduction half reactions are listed. So we have to look at the guy going this way. So that is negative zero point 44. Now, I put this negative here in here because we want to convert this to an oxidation because in this anode oxidation that reduction occurs and that's why we have the negative sign here. So what we get is these negatives become a positive and we basically add this guy to this guy and we get zero point 37 volts.
