    i know how to make a 3 bit unsigned one, but im confused about how to make it so that it compares signed numbers, 2's complement*

    Think about what 2's complement is (not the "invert-and-add-one" monkey recipe, but what a base-N radix-complement representation means) and, more importantly, why it is favored on machines that can already do unsigned arithmetic and operations.

    If that fails, then make your yourself a truth table and solve it just like any other random six-input function.
