If you give me a number and a string, I'm going to concatenate them together, it's really different operations, but nonetheless, it's what it's going to do.

如果给的输入是一个数字和一个字符串，我将会把它们连接在一起，这实在是不正确的操作，但是无论如何，它就是会去这么做。

As we saw before, it simply concatenates them together and gives me back a longer string.

和我们之前学过的一样,这个操作会把两个字符串连接起来。

All right? And if you want to do other things, whoops, sorry-- and add them together, we will get out, again, a concatenation of that string. And these will, we'll let you work through the variations, but these are the simple expressions we can use.

对不对？如果你想要进行一些别的操作，哦，对不起-是加到一块，然后结果值也是，两个字符串的链接，这些会，我们会让大家慢慢学习变量，但是这些是我们能用的最简单的表达式。

I don't happen to like this, but he thinks that is, give a combination of a number multiplication in a string, this will in fact give us back a new string with that many replicas, if you like, of the string concatenated together.

我不喜欢这么做但是他认为,也就是说，返回一个字符串的,某个特定数字的倍数，这实际上会返回一个新字符串,一个原来的字符串的很多复制品，连接到一块的一个字符串。

It says, if I want to print out something I built in Cartesian form up here, says, again, I'm going to pass it in a pointer to the instance, that self thing, and then I'm going to return a string that I combine together with an open self and close paren, a comma in the middle, and getting the x-value and the y-value and converting them into strings before I put the whole thing together.

这不仅仅是个列表,它是怎么来做的？,流程是：如果我想要返回,一些已经在笛卡尔模式下建好的值，好，再说一遍，我首先要传入一个,指向实例的指针,也就是，然后我会返回一个,由开括号，闭括号,中间的一个逗号,以及提前转换为字符串格式的。
