Clarified examples regarding return values (#44735)

* clarified example for return values on methods

* Fixed small type - SimpleMathExtension

* Made a separate class for SimpleMathExtension

* Swapped the order of the sentences describing the examples

 Sometimes, you want your method to return more than a single value. You use *tuple types* and *tuple literals* to return multiple values. The tuple type defines the data types of the tuple's elements. Tuple literals provide the actual values of the returned tuple. In the following example, `(string, string, string, int)` defines the tuple type returned by the `GetPersonalInfo` method. The expression `(per.FirstName, per.MiddleName, per.LastName, per.Age)` is the tuple literal; the method returns the first, middle, and family name, along with the age, of a `PersonInfo` object.
