Ok, I see your point, fair enough.
My subtle point was this, where I see no difference (set aside "homework", as for me working yourself, is something a serious student of anything would do - wether beeing told to or not)
In physics class, we are taught HOW we can DESCRIBE the physical interactions, by timeless laws and intial conditions. The WHY is simply - beacuse it's was the scientific process led us. For thoose seeking deeper understnadings and want to expand, you are on your own [open problem].
In MA, we are taught HOW do to thins. The WHY is OFTEN - because this is our style, sometimes you can can an more explanation but not necessarily a unique one, but an arbitrary one. So if you seek the constructing principles more deeper, you are again on your own [open problem as well? or?].
This is how I feel. But I see nothing wrong with! I just think it is similar to anything else. I am rarely satisfied by the superfical HOWs.
