The instructions above describe the new way of installing this extension using wfLoadExtension() If you need to install this extension on these earlier versions (MediaWiki 1.24 and earlier), instead of wfLoadExtension( 'Financial Mathematics' );, you need to use:

require_once "$IP/extensions/Financial Mathematics/Financial Mathematics.php";

In fact please ignore any message about how to install the extension on MediaWiki 1.24 or earlier. The extension does not work on MediaWiki 1.24 or earlier.
