  question: If you are driving the bus, and bus initially has 10 passengers. At first
    bus stop 4 passenger gets off the bus and 3 get on to the bus. At second bus stop,
    3 passenger get off the bus and 5 get on the bus. Now bus reached to it's final
    stop. Answer the following questions, Who is driving the bus and how many total
    passenger will get off from the bus at final stop?
output: "The bus reached its final stop with the driving bus. The number of passengers
  on the bus at the final stop is \ncalculated as follows:\n\nInitial number of passengers
  = 10\nPassengers that got off at the first bus stop = 4\nPassengers that got on
  at the first bus stop = 3\nNet change in passengers at the first bus stop = (4 -
  3) = 1\n\nPassengers that got off at the second bus stop = 3\nPassengers that got
  on at the second bus stop = 5\nNet change in passengers at the second bus stop =
  (5 - 3) = 2\n\nTotal net change in passengers = Net change at the first bus stop
  + Net change at the second bus stop\n= 1 + 2 = 3\n\nSo, the total number of passengers
  on the bus at the final stop = (Initial number of passengers + Total net change
  in \npassengers)\n= (10 + 3) = 13\n\nTherefore, the total number of passengers who
  got off from the bus at the final stop is 1, as calculated above."
