conversations.value: Several birds were sitting in the branches of a crape myrtle tree.  There were three times more cardinals than bluebirds, but half as many swallows as bluebirds. If there were 2 swallows, what is the total number of birds in the crape myrtle tree?
  Give me a detailed solution.

conversations.value: With half as many swallows as bluebirds, there are 2*2=4 bluebirds.
  With three times more cardinals than bluebirds, there are 3*4=12 cardinals,
  If there were 2 swallows, then the total number of birds in the crape myrtle tree is 2+4+12=18 birds.
