Hi pay2cEM. Welcome to hubpages. The number next to each hub is the hubs score. The better and unique the content on your article is the greater the score. There are various resons for the score to be higher or lower but the basis is, the better the hub the greater the score. You also have a score on for your account (59 at the moment I´m writing this reply). That is your score (maximum 100) and will change with time. The better writer and active you are the greater your score will be.
