conversations.value: Find the answer to the math problem: In Rodrigo's classroom in the morning there are red chairs, yellow chairs, and blue chairs. There are 4 red chairs. There are 2 times as many yellow chairs as red chairs, and there are 2 fewer blue chairs than yellow chairs. In the afternoon, Lisa borrows 3 chairs.  How many chairs are left in Rodrigo's classroom?
conversations.from: assistant
conversations.value: There are 2 * 4 red chairs = 8 yellow chairs.
  There are 8 yellow chairs - 2 = 6 blue chairs.
  Total in the morning there were 4 red + 8 yellow + 6 blue = 18 chairs.
  After Lisa removed chairs there were 18 - 3 chairs = 15 chairs remaining.
