Coding is all around us in the real world if you know where to look. This informative book shows young readers how machines such as scanners at the grocery store use coding, and how they connect to databases for inventory and for payment. Easy-to-follow text breaks down "IF, THEN" statements and other rules of coding that make things such as light sensors on street lights and 3-D printers work. -- Publisher description.
