Using logic gates, Boolean equations, or latches, create a circuit diagram for a binary calculator that completes the addition and subtraction of two four-digit inputs and outputs the result.

Hint: You will need to include a bit that depicts whether the circuit is to perform addition or subtraction along with the 8 input bits.

Pleaser answer differently from any answer that is out there already. I would like to see how it is done from a different answer entirely. Thanks!
