accept that (given that long multiplciaton and division have applciations
in manipulating agebraic expresions too). But I am convinced that if you
are goign to assume that clacualtors are everywhere you should teach kids
why said calculators do not always give the right answers and how to
avoid such problems.

When I was in hs, calculators weren't seen until or 12th grade. When it was
impractical and too time consuming to work out every log, trig function, or laborious
arithmetic operation. Kids have been bringing calculators to school for 2 decades
probably, and I for one see that as a travesty.
