+ These methods are called to implement the augmented arithmetic assignments
(``+=``, ``-=``, ``*=``, ``/=``, ``//=``, ``%=``, ``**=``, ``<<=``, ``>>=``,
``&=``, ``^=``, ``|=``). These methods should attempt to do the operation
in-place (modifying *self*) and return the result (which could be, but does
not have to be, *self*). If a specific method is not defined, the augmented
- operation falls back to the normal methods. For instance, to evaluate the
- expression ``x += y``, where *x* is an instance of a class that has an
+ assignment falls back to the normal methods. For instance, to execute the
+ statement ``x += y``, where *x* is an instance of a class that has an
:meth:`__iadd__` method, ``x.__iadd__(y)`` is called. If *x* is an instance
of a class that does not define a :meth:`__iadd__` method, ``x.__add__(y)``
and ``y.__radd__(x)`` are considered, as with the evaluation of ``x + y``.
