conversations.value: I'm stuck on this math problem: Diane gave a number train a starting value of 20. This starting value plus half the number was divided by 5 and the resulting value was multiplied by the starting value minus 12. What was the final value of the number train?
  Can you help?

conversations.value: If Diane gave a number train a starting value of 20, half the number is 1/2*20=10
  The starting value plus half the number is 20+10=30
  This starting value plus half the number was divided by 5, giving a total of 30/5 = 6
  The starting value minus 12 is 20-12=8
  The resulting value after dividing by 5 was times by the starting value minus 12, a total of 8*6 = 48
