conversations.value: Explain how to solve this math problem: John has to restring 3 basses with 4 strings each, twice as many guitars which have 6 strings each, and 3 fewer 8 string guitars than the normal guitars.  How many strings does he need?
conversations.from: assistant
conversations.value: The basses take 3*4=12 strings
  He restrings 2*3=6 normal guitars
  That takes 6*6=36 strings
  He restrings 6-3=3 guitars with 8 strings
  So that uses 3*8=24 strings
  So he uses 12+36+24=72 strings
