报价和列表的区别是什么？

I know that you can use ' (aka quote) to create a list, and I use this all the time, like this:

> (car '(1 2 3))
1

But it doesn’t always work like I’d expect. For example, I tried to create a list of functions, like this, but it didn’t work:

> (define math-fns '(+ - * /))
> (map (lambda (fn) (fn 1)) math-fns)
application: not a procedure;
  expected a procedure that can be applied to arguments
  given: '+

When I use list, it works:

> (define math-fns (list + - * /))
> (map (lambda (fn) (fn 1)) math-fns)
'(1 -1 1 1)

Why? I thought ' was just a convenient shorthand, so why is the behavior different?
