    I'm trying to figure out how to make a Half-adder using a 2 to 1 multiplexer and I'm also trying to find a way to build a modulo-59 using flip-flops. Any help will be appreciated. Thank you

    Well for the half adder you can write out the truth table and figure out how your are going to write the functions for the sum and carry with a multiplexer.

    If you think about how many bits you will need to represent 59 in binary with, you can figure out how many flip-flops you will need to use. From there you can decide on what happens when the outputs hit 59.
