What I want to do is make the output from this code be 200-"output" so that if the out put is 10 what is seen on page is 190. 

$row = mysql_fetch_array($result) or die(mysql_error());


// Echo some results

echo $row[0];

// Echo some results
echo (200-$row[0]);

Or you can assign the output to a variable and substract:

// Echo some results
$output = $row[0];  
$subtractionValue = 200 - $output;
echo $subtractionValue;
