+   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``.
