Implicitly added the formula into the description, so now you don't necessarily need to go to Wikipedia for the formula.

Why did you mark it as a issue? It should be suggestion not issue

replaced with basic (not sure what base would mean here: a lame base sorting method...)

some languages do, some dont. re-raising here with a list of affected languages

Those are just some names I gave in the description to describe the requirement in words; they are not code fragments so language conventions don't apply.

I'm pretty sure this is not a good thing to do. This will make the description not lang-agnostic. This can cause a very messy description markdown just for handling formatting for different langs. Messy description is hard to maintain.
