    3. An expression (e.g. 2+3)
  4. If the user does not answer a question and try to submit the quiz, the webpage must display a note saying, "Answer question [number]." The [number] should be replaced with the question number which is unanswered.
  5. Once the user answers ALL the questions, and upon clicking the Submit button, the webpage must display a message saying, Your score is [score] out of 10. [score] must be replaced with the number of of correct responses.
