Here is my jQuery:
$(\'.ask\').click(function() {
    $(\'.addtitle\').slideToggle(\'fast\', function() {
    // Animation complete.
    });
});
<         
        $('.ask').click(function() {
  var $this = $(this);
  $this.find('.addtitle').slideToggle('fast', function() {
     // Animation complete.
     if($this.text() === '-')
        $this.text('+');
     else
        $this.text('-');
  });
});
                                                                        You can do it using .next() and .toggle() like this:
$('.ask').toggle(function() {
  $(this).text('-').next('.addtitle').slideDown('fast');
}, function() {
  $(this).text('+').next('.addtitle').slideUp('fast');
});
.next(selector) get the next sibling if it matches the selector, if there may be something in-between then use .nextAll('.addtitle:first'), .toggle() cycles between the functions you provide on each click event, so it'll swap the text and slide appropriately every click.
