## Main Question or Discussion Point

Hi

I'm a layman so please keep your reply as simple as possible. Thanks.

They say that a CPU has built-in circuitry to do simple arithmetic operations such as addition, subtraction, etc. and logical operation such as greater than, less than, etc. I don't understand how could some circuit(s) do these things? Could you please explain it with some simple example? Thank you for your time and help.
