global $HTTP_POST_VARS;
$x=0;
if (isset($HTTP_POST_VARS["operation"])==TRUE)
{
switch($HTTP_POST_VARS["operation"])
{
case 'plus':
$x=$HTTP_POST_VARS[num1]+$HTTP_POST_VARS[num2];
print $x;
break;
case 'minus':
$x=$HTTP_POST_VARS[num1]-$HTTP_POST_VARS[num2];
print $x;
break;
case 'mm':
$x=$HTTP_POST_VARS[num1]*$HTTP_POST_VARS[num2];
print $x;
break;
case 'divided':
$x=$HTTP_POST_VARS[num1]/$HTTP_POST_VARS[num2];
print $x;
break;
}
}
