I was just assigned a school project for engineering. The project entails me adding three 3-digit binary numbers together to get an output (ex. 101 + 001 + 111). I don't have a huge understanding with electronics quite yet, but I know that half adders are used to add one bit binary numbers (i think). So all in all i'm just really confused on how to go about this with my limited knowledge and would love some expert advice. Thanks!
