-To use a value returned from a method, the calling method can use the method call itself anywhere a value of the same type would be sufficient. You can also assign the return value to a variable. For example, the following two code examples accomplish the same goal:
+The examples above are expression bodied members. Expression bodied members return the value returned by the expression.

 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.
