conversations.value: Break down this math problem: There are 50 passengers on a bus.  At the first stop, 16 more passengers get on the bus. On the other stops, 22 passengers get off the bus and 5 passengers more get on the bus. How many passengers are there on the bus in total at the last station?

conversations.value: There are 50+16=66 passengers at first.
  Then 66 - 22 = 44 passengers remain.
  Since 5 more passengers get on the bus there are 44 + 5 = 49 passengers on the bus.
