The essence of programming is computation—we want the computer to do some work with the input (the data we give it). Very rarely do we write programs that tell us something we already know. Even more rarely do we write programs that do nothing interesting with our data at all. So, if we’re going to write programs that do more than say hello to us, we’re going to need to know how to perform computations, or operations on our data.
