One certainly can appeal to the English meaning of "sum".
The standard clearly specifies the cases in which the result of
"+" is something else, or is undefined.  In other cases, common
sense suffices.  I suppose it could have defined it in a way that
explicitly specifies that 2 + 2 yields 4, but it hardly seems
necessary.
