Dear Group, I don't know whether this "feature" is widely known or not, but it surely gave me an hour of scratching my head, buried deep inside a calculation: In[7]:= n = .5; x = 1; ax = 1; {(ax^n), x^n, ax^n - x^n} Out[10]= {1, 1, 0} In[11]:= max = 1; {(max^n), x^n, max^n-x^n} Out[12]= {1, 1, -1} This inconsistency happens only if exponents are typed in as real superscripts with Ctrl+^. A FullForm reveals an underlying Times in the last case, which ultimately is responsible for the wrong answer. Furthermore, max^n does not work as intended if typed and evaluated in one call, as follows: max <Ctrl+^> n <enter> x <Shift+Enter> because it is interpreted as a product of max^n and x.
