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
