question 2

Let In[9]:= f1 = (o - 8)^4 - (e + 4)^8; In[10]:= f2 = (x - 8)^4 - (y + 4)^8; Then In[15]:= ?f1 Global`f1 f1 = -(4 + e)^8 + (-8 + o)^4 In[16]:= ?f2 Global`f2 f2 = (-8 + x)^4 - (4 + y)^8 Why the f1 and f2 appear different? The ordering has to do with the letters? That is, First "e" then "o" in f1, and "x" first and then "y" in f2 rather than with the order of 4 and 8? Thanks. Dimitris
