conversations.value: I would love to understand how to solve this problem: Trevor buys three bouquets of carnations. The first included 9 carnations, and the second included 14 carnations. If the average number of carnations in the bouquets is 12, how many carnations were in the third bouquet?
  Can you explain?

conversations.value: There are 3 bouquets.
  The total is the average times the number of bouquets, or 12*3=36.
  There are 9+14=23 accounted for.
  The third included 36-23=13 carnations.
