               SUBTOPIC: SIMPLE ESTIMATION

                          Estimation helps when you do not need the exact number and just want a quick idea. For
               example, if you’re estimating how many books are in the library, you might guess based on what you see
               rather than counting each one.

               Example 1: Estimating the Number of Books in a Library

                     You know there are about 300 books on each shelf.
                     There are 10 shelves in the library.

                     Estimate: Instead of counting every book, you multiply 300 by 10 and estimate there are
                       around 3,000 books in the library.

               Example 2: Estimating Guests at a Party

                     You see that each table at a party has about 8 people.

                     There are 12 tables.
                     Estimate: Multiply 8 by 12 to estimate that there are about 100 people at the party
