Note that Literal has been renamed HoldPattern.  (In case you try to
decipher Jonathan's code.)

Hi JM,

You can copy and paste the following expression into your notebook and
if
 you evaluate it at the very beginning you will get polynomials in their

standard book form including your c+1.

Unprotect[Plus];
Format[Literal[Plus[p__]]]:=Module[{s1,s2},s1=Hold[p];s2=Reverse[s1];
ReplacePart[HoldForm[Evaluate[s2]],Plus,{1,0}]/; OrderedQ[s1]&& s1=!=s2]

Subject: [mg35578] [mg35541] [mg35509] Output of left-hand side of expression

Hello
This is really simple but I cannot find in manuals. (Honestly!)

Q. How do I display the left-hand side of an expression

currently I do

In[148]:=
M=C+1
Out[148]=
1+C

but I want

Out[xxx]=
M=1+C

I need this so that I can copy/paste the entire expression into a doc.
so
that it is complete - not just the right hand side or result.

Is there some magic command that can do this? or system default?

Thankyou.
