The action of bit-serial arithmetic circuits is often explained in purely pictorial terms. In contrast, this paper describes an attempt to deal with the systematic development of bit-serial arithmetic circuits within a mathematical framework which we have previously used to develop parallel circuits. A well-known bit-serial adder is formally shown to implement the specification of an adder, without any recourse to detailed arguments about snapshots or specific arguments about sequences of inputs.
