[csswg-drafts] [css-values-5] What is meant by the distinction between "math function" vs. "function that evaluates to a <number>." (#11204)

weinig has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-values-5] What is meant by the distinction between "math function" vs. "function that evaluates to a <number>." ==
In a few places in CSS Values and Units 5, for instance for [`media-pogress()`](https://drafts.csswg.org/css-values-5/#media-progress-func), there is a not that reads:

> NOTE: [media-progress()](https://drafts.csswg.org/css-values-5/#funcdef-media-progress) is not a [math function](https://www.w3.org/TR/css-values-4/#math-function); it’s just a function that evaluates to a [<number>](https://www.w3.org/TR/css-values-4/#number-value).

Even though I just implemented `calc()`, and I feel I probably should understand what that means, I don't really understand the distinction being made here.

Are there different behaviors that would be observable if were "a math function"? Different places it could be used?
