That sounds like the approach of an orthodoxy rather than of a
scientific research community.

It seems to me that you are saying that avoiding irrelevancies is
pointless.  For example, I believe you have declared that leaving out
the circle functions is pointless, in a class that is not yet ready
for trigonometry.

If that is a valid representation of your point of view, then I must
agree that your conclusions are consistent.  I would not want to use J
with this "non-pointless" approach, either.

That is unfair, since the comparison is lacking in substance.

So, I set about to incorporating some substance, but I just now did
some web searches to see what the formal definition of "standard
algebraic notation" is.  I did not find anything comprehensive,
concise and relevant.  My impression, though, is that some aspects
must vary from country to country (and in some cases from topic to
topic).

For that matter, contrast:

2dx+3dy

with

2dm+3km

or, consider:

x0 + x1 + x2
e0 + e1 + e3
2x0 + 2x1 + 2x2
2e0 + 2e1 + 2e3

The resolution to these issues, of course, is to be very careful what
we write (for example, if the class uses scientific notation we avoid
using e as a variable in a context where it might be confusing).
