    $\begingroup$ What have you tried so far ? do you have a gate level diagram of the half adder and the full adder ? Please add both to the question. If the full adder requires an XOR gate, the XOR gates from multiple half adders can be used. etc... $\endgroup$

    $\begingroup$ Homework sounding questions require your efforts to solve it be shown in the question itself. $\endgroup$

  • $\begingroup$ I've tried and I got 6 half adders to make a 3 bit full adder, I just wanted confirmation. $\endgroup$ Sep 28 '21 at 12:11
