conversations.value: I'm completely lost with this math problem: Nick had twice as many candies as George. Then George ate 5 candies. Now George has 3 candies left. How many candies does Nick have?
  Can you give me a hand?

conversations.value: George has 3 candies now but he already ate 5. So he had 5 + 3 = 8 candies at the start.
  Nick had twice as many candies as George, so he had 2 * 8 = 16 candies originally.
