Good Math Puzzle for ALL AGES.

Consider this a test to see if you can add numbers in your head quickly. I find it kind of strange that many people can't do this puzzle in 4 seconds. After reading the question, you have only 4 seconds to answer:

 

Jon the bus driver drives a bus with 10 passengers initially. On the first stop, Jon lets off 3 passengers and takes in 5. Then on his next stop, he takes in 6 and lets off 4 people. On the next stop he takes in 5 passengers, and drops off 3. Then on the next stop he takes in 5 passengers and lets off 3 passengers. On the next stop, 8 passengers get on, and 2 passengers get off. Then on the next stop 12 passengers get off and 3 get on. Finally, on the last stop before he reaches his end terminal, he lets off 6 passengers and takes in 4.

 

Now the question is: How many bus stops where there in all?
