Cameron had 12 DVDs last year and now has more than 25, which means he has at least 26 DVDs this year. The difference in the number of DVDs he has compared to last year can be calculated as 26 - 12 = 14. Therefore, the possible values for how many more DVDs Cameron has this year than last year range from 14 to any number greater than 14, depending on how many DVDs he has beyond 26.
