Jen scored 10 more than Bryan while Sammy scored 2 fewer than Jen. If the math exam has 35 points in all, how many mistakes did Sammy make?
conversations.from: assistant
conversations.value: Jen scored 20 + 10 = 30 on the exam.
  Sammy scored two less, so his score was30 - 2 = 28.
  Thus, Sammy made 35 - 28 = 7 mistakes.
