conversations.value: This math problem has got me stumped: John climbs up 3 flights of stairs.  Each flight is 10 feet.  He then climbs a rope that is half that height.  Finally, he climbs a ladder that is 10 feet longer than the rope.  How high up did he go?
  Can you show me the way?

conversations.value: He climbed 3*10=30 feet of stairs
  He then climbed 30/2=15 feet of rope
  Finally, he climbed a 15+10=25 foot ladder
  So in total, he climbed 30+15+25=70 feet
