conversations.value: This math problem has got me stumped: A pole is 20 meters long. It got cut in a way that left it 30% shorter. How long is the pole?
  Can you show me the way?

conversations.value: The cut-away part of the pole is 30/100 * 20 = 6 meters long.
  So the pole is left at the length of 20 - 6 = 14 meters.
