    That is because nobody has made adders and subtractors from discrete components since the late 1950's or the early 1960's when integrated circuits first appeared. This was before there was such a thing as a schematic in electronic form. I suggest textbooks from that era like Norman Scott's classic work on Analog and Digital Computer Technology.
