How do you apply the Guesstimate technique to estimate complex quantities in math?
Have you ever wondered how to estimate the number of piano tuners in Chicago, the weight of the Eiffel Tower, or the length of the Great Wall of China? These are examples of complex quantities that are difficult to measure directly, but can be approximated using a problem-solving strategy called the Guesstimate technique. In this article, you will learn what the Guesstimate technique is, why it is useful, and how to apply it to any math problem that involves estimation.
