    So I have a homework problem where I have to make a 1 bit adder using a 4:1 Mux. Anyone have any ideas on this?

    Let's have a quick review.

    A one-bit adder has 2 input bits and one result bit. The two input bits represent one of four possible conditions.

    A 4:1 multiplexer has four inputs and one output and TWO select bits. The two select bits select one of four possible constants (either 0 or 1) which can be routed to the output.

    Are you starting to get the idea?
