A bus is driving down a street. There are 13 people inside,including the driver. 7 get off and 4 get on at the 1st stop. 3 get off and 5 get on at the 2nd stop. How many people are on the bus now?

From "Megaman Battle Network 5".

[Mephistopheles]

x = 13 - 7 + 4 - 3 + 5

(thinking part)

x = 12

So, there's your answer.

But, it says "A bus is driving down a street." how can a bus drive itself or something else? it should say that a bus is *moving* or *going* down the street, or that a man/woman is driving a bus down the stream. Is it wrong spelling or the whole thing is incoherent on purpose?

Math says 12
