You got me there.

But how about some simple expression that does not contain any 
Mathematica-unique syntax or commands -- just a sequence of input 
keystrokes that would be interpreted as a meaningful algebraic or 
mathematical expression by someone who was reasonably knowledgeable in 
math and algebra, but had never encountered Mathematica?
