Default Using multiplexer as adder

Hi all, I'm new to this forum and since this was the first link on google search result I'd thought I register in case I need more help with learning in future. I know this post is old and understand you guys generally frown upon giving the answer straight away so here's my first attempt in sketching a logic diagram for a 1-bit full adder, using two 8-to-1 multiplexers.

Any constructive feedback is appreciated!!!!

Welcome to AAC.

We do frown on hijacking threads like this 2 year old one -

Looks like you correctly figured it out. This particular problem manages to stop some students dead in their tracks.
First comes the hardware, then the software.
