No, I got my knowledge in that area from math. Of course there may be
different notation used in different math books, but for basic math
calculations with numbers I think you should use the standard notation
for just that.

If some algebra books use "simplified notation" the best thing to do
might be to burn them. There is no need to complicate things with
unneeded extra notations that makes it hard to read the books. Algebra
is not so much about that. (But of course, sadly enough I have seen
books using their own subfield notation.)

I never use LaTeX so I do not know. But why do you refer to LaTeX here?
