Default php take get variable and dynamically set values

Code:
if ($page == 2) {
  $minimum = 10;
  $maximum = 20;
} else {
  $minimum = 0;
  $maximum = 10;
}
I have a variable "$page" in my script, if I $page is 3 then the minimum and maximum values would need to be 20 and 30 respectively. Is there a way I can amend the code above to make it more dynamic that just purely having if statements catching the $page value and setting the values as I am just now?

Any help is very much appreciated,
Picco

Default

$page = (isset($page)) ? $page : 1;

$minimum = ($page - 1) * 10;
$maximum = (($page - 1) * 10) + 10;
