In[8]:= (1 + I)* (1 - 3 I) <===== upper case
Out[8]= 4 - 2 i <======= lower case
With upper case I in In, it works, but uses the lower case i in Out.
In[11]:= (1 + i)*(1 - 3 i) <==== lower case
Out[11]= (1 - 3 i) (1 + i) <===== not multiply?
With lower case i in IN, it doesn't Works.
It seems inconsistent (or not?)
thanks in advance.
