Example of a simple program

new to programming here. i am reading SICP right now and have seen a couple of MIT videos on python but i was just curious if anyone could give me an example of how a program is written. as in the actual process beginning to end. it kinda boggles me that its all math and simple equation but i would love to understand it. thank you.
