conversations.value: I'm stuck on this math problem: Cooper makes 7 apple pies a day. He does this for 12 days. Ashley then eats 50 of his pies. How many apple pies remain with Cooper?
  Can you help?

conversations.value: The number of pies Cooper makes in 12 days is 7 pies/day * 12 days = 84 apple pies.
  After Ashley eats 50 of them, there are 84 pies – 50 pies = 34 apple pies.
