I suppose it depends on the university, department and teacher, but we were allowed to use calculators on math exams. Of course, they weren't helpful at all - if you knew how to solve the problem the calculations were so simple that you didn't need a calculator, if you didn't, you couldn't solve the problem no matter how good your calculator was. For similar reasons, we were also allowed to bring in any books, notes etc. to exams. If you didn't have a good understanding of the subject, they weren't helpful at all as there was no time to start figuring out things, but if knew stuff, you didn't need the books and lecture notes at all or only for reference. Sometimes I miss those times.
