Yup.
Quite a bit of educational effort was expended by my profs
to teach "effective simplification" of abstract and numeric equations
to have an incling of expected results.
Same for how the various parameters of an equation amplified into the
final outcome.
With solution blackboxes this is a lost art.
( actually started with calculator use )
What surprised me in a recent discussion elsewhere is that
number crunching used in connection with trial and error optimisation
is seen as the primary/sole driver for tech progress.
No understanding for the potence of abstraction and
theoretical understanding.
