 **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 invoke the value method and don't do anything with the result then the code still occurs and runs but whatever result comes of it will be discarded. 
 2. What happens if you use a void method as part of an expression? For example, try `System.out.println("boo!") + 7;`.
+* If you try to use a void method as part of an expression then you will get a compile-time error. This is because the void method doesn't produce a value that can be used in an expression. The command System.out.println("boo!") is a void command so adding a 7 won't do anything until the 7 is inside the parenthesis with the "boo!".
