 **Questions to answer in the README.md via Markdown:**
 1. What happens if you invoke a value method and don’t do anything with the result; that is, if you don’t assign it to a variable or use it as part of a larger expression?
+- If you call a value method but don't assign the value in the method to a variable, the value will not be used. The program will still compile and run.
 2. What happens if you use a void method as part of an expression? For example, try `System.out.println("boo!") + 7;`.
+- Compilation error, method println does not return a value.
