Just wanted to point out that this is not friendly for beginners. A beginner will be lost between a lot of "\frac"s and "{}"s (I don't know the name in English, sorry). Been there

The problem is that this is a really tiny subset of what you can write with LaTeX, even for high school students it won't be enough. I'd much rather use something like https://www.codecogs.com/latex/eqneditor.php as a beginner.

Yep - even 'min' is missing. `min_` becomes `m \in _`, seemingly no way to force it to work, `{min}` or `\min` don't.

{} are "brackets"/"curly brackets" :)

No, [ ] are brackets; { } are braces.

(Disambiguating with an adjective does make it ok to use either -- "Curly brackets" are still { }, and "square braces" are still [ ] )

No, they aren't. () are brackets, [] are square brackets, {} are curly brackets. 'Brackets' always refers to () unless specifically you say 'square'.

Stop imposing your stupid American stuff on people.

I agree with your content, but not your tone. I'd like to add that one often hears "round brackets" as an unambiguous terms for the first category. And where's love for angle brackets <chevrons>?

There are substantially more Americans than people in any other English-speaking country, and, to top it off, we're on an American forum.

It's not "stupid" to assume the dialect we're using is American English. Why the aggressiveness?

Because the cultural ignorance you are showing is annoying. There are vastly more people speaking english in the world than there are US Americans. On top of that: Most of the Americans are speaking spanish and portuguese. America != US America for one.

Thanks! :)

No, they won't.
