 **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?
-2. What happens if you use a void method as part of an expression? For example, try `System.out.println("boo!") + 7;`.
+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? 
+<br>Answer: Java/IntelliJ gives you a warning, but aside from that the method is executed and the value is discarded.
+2. What happens if you use a void method as part of an expression? For example, try `System.out.println("boo!") + 7;`. 
+<br>Answer: Compile error. Void methods don't return values, so they cannot be used in expressions or as values in variables.
