Go to the page number 4 of this slide.
I know how pencil and paper multiplication algorithm works.
However, I kept thinking but could not come up with a circuit for it(array multiplier circuit). Because I could not "idk what to say" it.
This has happened to me a lot. I study with a textbook and laptop and sometimes I suspect that usage of laptop is causing loose focus leading to these issues. However, I am not sure.
I'd be glad to get any help here.
