Subtracting from SELECT Count(*) strings

[exponder]

I'm trying to get php to subtract the output from a query count string. I've tried many various ways. And out of options, could anyone point me in the right direction? A guide.. or advice perhaps.

I'm trying to subtract by 2, from the IPBoard members.

code;

<?php
mysql_connect("localhost","UUUUUUUU","PPPPPPP"); 
mysql_select_db("DB_NAME"); 
$query = "SELECT COUNT(*) AS numrows FROM ibf_members";
$nummembers = mysql_query($query) or die("Select Failed!");
$nummembers = mysql_fetch_array($nummembers);
?>
Members: <? echo $nummembers[0]; ?>

Thanks for any help!

 <?php 
mysql_connect("localhost","UUUUUUUU","PPPPPPP");  

mysql_select_db("DB_NAME");  

$query = "SELECT COUNT(*) AS numrows FROM ibf_members"; 
$nummembers = mysql_result(mysql_query($query),0); 
$result = mysql_query($query) or die("Select Failed!");
$sub=$nummembers-2;
?> 
Members: <?php echo $sub; ?>
