Binary addition is the corner-stone of computation. This simple network
performs serial addition of two three-bit numbers.
To test this network, set the input values. The diagram shows Input A set to 110 and Input B set to 011 (the output would be 1001). Single step the network 5 times to perform the calculation. Any number of additional input and output units may be added. The number of steps required to perform the calculation is always one greater than the number of output units.
