Ha. According to my daughter (who got the full truckload of high-school math here, unlike her brothers) - it's THE way to teach Math in the US schools... The textbooks are written in the "take this, put it here, - voila, here's your answer" style - so, they can't be of much help, either.

So, eghem... you'd have to fire about 90% of the teachers... :)

Oh, well... at least, not all of them forbid asking questions...
