I believe the confusion with my claim is that I thought the oddity in 
question was that -3/2 != 0-3/2, but I believe you took the other half 
about exponentiation as the oddity in question that -3**2 == -(3**2). My 
original comment was to say that unary - was higher precedence than 
division because of C's ordering. With respect to the original question, 
then my answer was poor as I ignored the exponentiation part. Since we 
tacked this on, my answer was to be an implicit zen answer of "because 
it makes the most sense."

Sorry for the added noise.
