Realistically, 3 + + should give a syntax error as it's not a valid mathematical equation.
 
Anything generated from this equation is undefined.
 
I know some calculators use hitting the + button as a trigger to calculate anything in memory.
Looking at the Windows calculator, it seems to take a number then a operand as valid syntax to use the previous number as post number.
 
Thus
'3 +' = 6
'3 -' = 0
'3 *' = 9
 
Any further operand cancels out the previous.
Thus:
'3 + + + + - - - - * * *'  is equivalent to  '3 *' = 9
 
Strange ....
