conversations.value: Find the answer to the math problem: Donna made a cake to take to a party where the guests ate half the cake. The day after the party, she shared half the leftovers with her brothers. The following day, she ate one piece as a midnight snack. Twice as many pieces as her snack were left. How many pieces was the cake to begin with?

conversations.value: Donna had 2 * 1 = 2 pieces of cake left.
  Before her snack, there were 2 + 1 = 3 pieces left.
  Those 3 pieces were half the leftovers, so she had 3 * 2 = 6 pieces before sharing with her brothers.
  Those 6 pieces were half the party leftovers, so the cake was 2 * 6 = 12 pieces before the party.
