In Lecture, Dr. Lavelle said that we shouldn't really use the equation that simply finds the difference between the cell potential of the cathode and the cell potential of the anode, but I forgot the reason why. Can someone explain it to me please?

He said that it's better to do it the other way since it provides a better understanding of what's going on. Also, it's less confusing.

Also he might ask questions about the cathode and anode and the second method gives you a better understanding of what is going on.

When you use the equation E(cell) = E(cathode) - E(anode) it is easy to confuse the positive and negative signs of the values because for this equation both values are positive and you find the difference. In the other equation, the anode reaction has a negative value for the reduction potential, so it's easy to distinguish which reaction is which and helps give a clearer understanding.
