Ballparking: Solving Problems Quickly and Intelligently

The video introduces the concept of ballparking, a method of making quick, intelligent guesses instead of seeking perfect results. It is likened to baseball, where keeping the ball inside the ballpark is more important than hitting it perfectly. The technique is useful in conversations and essential for passing certain tests. The video demonstrates ballparking through two examples: estimating the most popular food in the world and solving a complex math problem similar to those found on the GMAT exam. The process involves using known information, making educated guesses, and eliminating unlikely options.
