when two cella are connected in series the positive terminal of the first cell is connected to the negative terminal of the other cell and the point where the two cells are connected is the point where the negative terminal of the first cell is connected to the positive end of the other cell so ,how this increases the voltage and why the point where the two cells are connected are not neutralizing
