How does an arithmetic logical unit work?

In other words, how does energy combined with metal perform logical operations? In the research that I did, I always assumed how “magic” happens, but there is usually no explanation of how a physical device can “understand” and execute processes of a logical nature. I think that it would be a good approach to first understand very simple devices as a calculator, but even with this I cannot understand (and feel completely amazed) how a circuit can be designed so that it can carry out “mental " actions. Thank!
