I can see what they*re trying to accomplish here, but they*re
  doing it ALL WRONG. Awfully worded question. Teacher*s Answer
  was terrible too. HERE*S HOW I WOULD DO IT: *If you have 8 and
  you have 5, can you get to 10? If so, what happens when you get
  to 10? Can you write that in a math formula? If so, try.* THAT*S
  how I would do it, if I was a math teacher who had to teach
  Common Core. The teachers aren*t prepared* neither are the
  quizmakers.
