pointers

Having very similiar code like so:

LINT_rep::Iterator::difference_type LINT_rep::Iterator::operator+(const Iterator& right)const
{
    return (this + &right);//IN THIS PLACE I'M GETTING AN ERROR
}

LINT_rep::Iterator::difference_type LINT_rep::Iterator::operator-(const Iterator& right)const
{//substracts one iterator from another
    return (this - &right);//HERE EVERYTHING IS FINE
}

err msg: Error  1   error C2110: '+' : cannot add two pointers

Why I'm getting an err in one place and not in both?
