You can put a variable there, and because it's not encapsulated in curly braces, as we just discussed, that essentially means it's accessible everywhere in that file.

So the open curly brace followed by the closed curly brace means everything inside of these curly braces should get executed, but only if that first condition is actually true.

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.

So that's just a little bit of a check for yourself, and it should make sense because what you're doing is you're calculating the difference between energy levels, so you just need to flip around which you put first to end up with a positive number here, and that's a little bit of a check that you can do what yourself.
所以你们总要确保括号，离得这项是正的，这是你们自己,可以做的检查，这事很有道理的，因为你们做的是计算能量差,所以你需要调整顺序来保证一个正数，这是你们自己可以做的检查。

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。
