<pre>@m.a.riosv: i don't agree,
imho this bug is about how to evaluate "-" signs in terms, as a property of the
following number or as a calculation statement for the term, e.g. -a^n either
as (-a)^n or as -(a^n),
if you go back you find some duplicates - 114922, 98248, 94580, 94568, 93983,
50596, 38999, 38824, 37271 - from which the last one - imho wrong - was sorted
out as notabug, nice discussion with the ever new question mathematical correct
vs. 'standard' vs. compatibility to old behaviour vs. compatibility with ex$el,

bz_status_NEW "
title="NEW - Make =-3^2 unambiguous by automatically adding brackets"
href="show_bug.cgi?id=114929">tdf#114929</a> formulates an enhancement request,
(mho: on the long run mathematical correctness / compatibility with school math
are unavoidable even if any conversion is hard, to get rid of the obstacle of
ex$el compatibility without hindering migration or data exchange two different
'calculation-modes' for calc would be necessary, with wondrous consequences for
the complexity towards the user)
not marking as duplicate as the 'solution' in 37271 is unsatisfactory,

title="NEW - Powers of negative numbers highly inconsistent"
href="show_bug.cgi?id=121398">tdf#121398</a> is about how to handle fractions as exponents, which comes up on
fractional exponents to negative values,
it's predecessors are 69293 and 44076 which are partly solved, 121398 still
waits for general solution, the tension between correctness and compatibility
is the same as above,
(mho: same as above)
the samples look somewhat similar and the issues may be related somewhere in
deeper layers of calc's mathematical concepts and procedures, at least they are
in the question 'math vs. compatibility', but on the surface it's two different
decisions, interpretation of "-" sign and handling of fractional exponents.</pre>
