What subject/field am I looking at that deals with things alike to the following: When I take a basic calculator apart, I see several objects, a main circuit board (I think that's what it;s called) a screen and the solar panel. How do all of these things work to make the mathematical manipulations that I punch into it? How does the screen know what to display? how does the circuit board know what numbers are being put in?
