Those men are constantly dashing around to find and execute simple instructions. An instruction might, for example, tell a little man to add or subtract two numbers or send a message to another little man. We call the set of instructions that a group of little men executes a program. The individual instructions of a program are simple, but a program's behavior can be surprisingly complex. Programs can solve difficult mathematical problems, simulate games, and communicate over long distances. With enough time one could even write a program that simulates the behavior of a little man!
