Well that's OK if it's a special child-friendly screening but not if the film is unsuitable for children - the parents are just using the cinema as a babysitter!

OK, so if I give you a curve that's not closed, and I tell you, well, compute the line integral, then you have to do it by hand.

如果给你们一条非封闭曲线，然后让你们计算线积分，你们必须动手一点点来计算。

Knowing that, I'm going to say, OK, how many pigs are there, well that's just how we're, however many I had total, minus that amount, and then I can see, how many legs does that give, and then I can check, that the number of legs that I would get for that solution, is it even equal to the number of legs I started with, ah! Interesting. A return.

它将给我返回头的总数，知道了这些之后我可以说好了,有多少猪呢，无论有多少组鸡的数目，我只要用总数减去那个值,之后我就可以知道一共有多少条腿,然后再把这个值和题目中的腿数相比较，看它是否等于一开始的腿数,啊！真有趣，有一个返回值。
