Half Subtractor

Creating the half-subtractor using CircuitMaker and test it to make sure it works correctly. Hook the inputs to two different hex key input switches and the outputs to two logic displays.
The half-subtractor works as long as the bits to be subtracted are in the least significant position, i.e. furthest to the right bits. To the left of this position, there is the chance that the place just to the right may borrow from it. Therefore the inputs can consist of the bits for a, b and a borrow.
