然后创建第二个原语，并将其连接到第一个原语，以此类推。

Then create the second primitive, and wire it up to the first, and so on.

And that in essence says, I've just created the equivalent of a new primitive.

Second thing they're going to do is let us suppress detail. And in essence what that does is, the functions, and we're going to look at a bunch of examples in a second, these functions are going to give us a way to, in some or in one way of thinking about it is to create new primitives.

第二件要做的事,是忽略细节,函数的本质到底是什么,我们将在接下来的几分钟，举一些例子，这些函数将给我们提供,一种创建原语的思考方式。
