We saw, associated with that primitive data, we have ways of taking data in and creating new kinds of data out, or new versions of data out, so we have operations.
我们可以取得输入的数据然后，创建新的类型的输出数据,或者新的版本的输出数据,这就是我们说的操作。

Just as in grade school when you're doing division and multiplication, you do it from left to right in terms of order of operations.
正像是在小学你做除法和乘法的时候,你毫不含糊地从左到右,按顺序做运算。

s not going in the future.-We are not going to get out of that, out of a lot of massive contraction. And massive contraction might cause some operations to perish. I knew some Anderson partners who were honest decent people who suffered terribly.
而且没有未来，-大规模缩减，And，it’,对我们来说没什么用处,而且会造成一些,行动的失败，我知道一些,诚实正直的安德森合伙人,损失惨重。

We've talked about data, we've talked about operations, and we've talked about commands or statements. All right?
我们学习过操作，我们还学习过,命令或者说是声明了，对不对？

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。

STUDENT: Standard order of operations, I guess take the multiplication first, and add the three.
学生：标准运算符的顺序，我猜是先做乘法，然后再去加3。
-
Down here, I've just got two things to merge, and then I've got things of size two to merge and then things of size four to merge. But notice a trade off. I have n operations if you like down there of size one.
但是n的大小是不同的，是吗？在这里我们只要合并两个元素,然后是合并长度为2的列表,接下来是合并长度为4的列表,但是观察一下之间的权衡关系。
-
O Right there, order n. So I have order n operations at each level in the tree. And then how many levels deep am I? Well, that's the divide, right? So how many levels do I have?
在这儿,所以我在树的每个层次都要做O的操作,那个这棵有多少层呢？,这是一个除法，不是吗？
