conversations.value: Can you give me some step-by-step instructions for this math problem: Trent walked 4 blocks from his house to the bus stop. He rode the bus 7 blocks to the library. Later, he came home the same way. How many blocks did Trent travel in all?
conversations.from: assistant
conversations.value: On the way to the library, Trent went 4 blocks + 7 blocks = 11 blocks.
  Trent came home the same way so he went 11 blocks + 11 blocks = 22 blocks.
