conversations.value: I need help with this problem:
  A carpenter made ten tables for this month. Last month, he made three fewer tables than this month. How many tables did the carpenter make in total?
conversations.from: assistant
conversations.value: The carpenter made 10 - 3 = 7 tables last month.
  So, the carpenter made 10 + 7 = 17 tables in all.
