Do you always flip the anode sign? If I want to add both reactions instead of subtracting them will i get the same answer?

If you want to add both reactions rather than subtract, then yes you flip the anode sign. This is because you are using reduction potentials, but oxidation is occurring at the anode, which is the reverse reaction of reduction. Therefore, you would have to flip the sign for the reaction occurring at the anode in order to add the anode and cathode reactions.
