-
And when we describe this in terms of talking about chemistry terminology, we would call the first one the 1 s, and 1 is in parentheses because we're talking about the first electron there, and we would multiply it by the wave function for the second one, which is also 1 s, but now we are talking about that second electron.
当我们用化学术语来,描述它的时候，我们称第一个为“1s“,括号中的1是因为我们,在谈论第一个电子,而且我们会用它的波函数，乘以第二个,第二个也是“1s“,但是我们现在谈论的是,第二个电子。
-
I just want to make mention of this in case there's ever doubt, generally parentheses do solve your problem as an arithmetic but do realize this is some lower level details we'll come back to over time.
是想告诉大家如果你对某些式子的前后运算关系不确定，就加上括号,这都是一些小细节,我们以后还是会再提到的。

You might recall from grade school sometimes you put things in parentheses so that your addition happens first, then your multiplication, otherwise multiplication would happen by default first.

-
And so, in fact, if I wanted the other version of it, in fact, if I do this right, 23 it's going to give me 23 because it does the multiplication first, if I wanted the other version of it, Python I need to tell it that, by using, excuse me, parentheses.
因此，实际上，如果我想换种做法，实际上，如果我去执行这个表达式，返回值是3,因为乘法会被优先执行，如果我需要换种做法，我需要告诉，用括号来告诉它。

And even though the syntax, the characters you are about to see on the screen and in programs today onward is a little more arcane, it's a little uglier looking, you've got semicolons and parentheses and fairly arcane syntax, realize that at the end of the day these are just arbitrary human conventions, the ideas are identical to this thing here.
可能你在屏幕上，编程中见识到的,语法，字符看起来非常晦涩难懂,甚至可以说是丑陋，像什么分号啊,括号啊等等，还有一些难七八糟的语法，但是到了最后，你会发现,这些都不过是一些人为约定而已，而蕴含在里面的编程思想跟这个例子并无二致。
-
But to translate this now to a language C, you've got some curly braces, you got an if, some parentheses, but now we're just building on some of the syntax we introduced before.
如果把它转换成C语言，你又会看到一些大括号啊，if啊，圆括号啊等等，我们只是借助,之前学过的语法规则。
-
But if it does take input, you have to provide it in the form of arguments or parameters, like print F takes, generally, inside of those parentheses.

-
But at the end of the day, the point of the slides is not to expect you to now go write programs in C but really to just remind you that, hey, if you ever get distracted from some of the minutia that is the semicolons, parentheses, and what is very new to many of you, it's really no different than the fun and games we implemented with Scratch last week.
但是最终，我们课件上讨论的主题,并不是让你现在就写一个C语言的程序,而是要告诉大家不要你被那些分号括号,还有一些从未见过的符号等一些细节搅得心烦意乱，因为它们本质上,和我们上周用Scratch做出来的游戏,并无区别。
