No it is not for removing elements. This method is used for select the elements that do not match the criteria are returned from the selection.

Let's say you have 5 list items on your HTML page:

<li>item 1</li>
<li>item 2</li>
<li>item 3</li>
<li id="special">item 4</li>
<li>item 5</li>

If you were to type:

$("li")

it will select all 5 of your list items
so in turn if we were to say 

$("li").css("font-weight","Bold");

it would give all 5 of our list items bold text

if we said 

$("li").not("#special")

it would return 4 out of the 5 list items, but it would not include the one with the id of "special"
Using our previous example we can chain these to say:

$("li").not("#special").css("font-weight","Bold");

and now all EXCEPT number 4 have bold text
