Of course it does! That's something we can all agree on. Negation does take priority over powers in all versions of the hierarchies I've seen. (-2)^2 = 4

Not so for Python:
>>> -2**2
-4

Yes for Prolog:
?- X is -2^2.
X = 4.

Yes for Unix bc:
bc 1.06

-2^2
4

Not so for Basic (all Sharp PC and Visual Basic):
-2^2
-4

Yes for Fortran.

Not so for Casio fx-115ES+.

The jury is still out on this one...
