conversations.value: Break down this math problem: A judge oversaw seventeen court cases. Two were immediately dismissed from court. Two-thirds of the remaining cases were ruled innocent, one ruling was delayed until a later date, and the rest were judged guilty. On how many cases did the judge rule guilty?

conversations.value: The judge dismissed 2 cases, leaving 17 - 2 = 15 cases.
  Of the remaining 15 cases, 2 / 3 * 15 = 10 were ruled innocent.
  One ruling was delayed, so the judge ruled guilty on 15 - 10 - 1 = 4 cases.
