As for the default school arithmetics, you're right, the expression doesn't follow the common conventions.


 * 1) math-babble on

However, general math is more than few memorizable formulae for kids. Not even "1+1=2" has to be absolutely true (modular arithmetic being an example). A basic concept of math is that one always analyses mental constructs within a certain system ("a theory") based on unproven/unprovable premises ( "axioms"). A same proposition can be then both true in one theory and false in another. A naive approach overall (as shown by Gődel's incompleteness theorems..), but that's the deal.

In practice one can define, or even redefine, their own operators. And here on wiki, there is this 'ability scaling' syntax:

(+ ) := ( + )

The right-hand expression uses common math conventions. Basically, a "(+" is a special 'ability scaling' operator on this wiki, not a combination of regular parenthesis and plus. That's why there should never be a space between the two symbols. It is a "scaling appendix" operator for the base expression, the reason of its existence being, umm, folklore :p
