My friend went to one of the best high schools in my country (Poland), where students would, on their own accord, practice using old Soviet math textbooks.
I got my hands on one of them where the task stated was usually something short, like: "доказать тождество", followed by a set of rather insane(at least for a highschooler) equations.
That bit about a dearth of equipment is true in most eastern block countries by the way. Case in point: the other day I asked my younger cousin, who's currently doing his master's, if they still use those multimeters with nixie tube displays like I did ten years ago.

They do.
