This is the cheapest calculator I can find that does logs in any base (not just 10 or e), which makes exams easy. It also does fractions seamlessly. speaking of, I've seen some people complain that it won't show decimel answers, but almost all calculators have a trick where you need to press shift and then = to get decimels rather than fractions for your answer. Inconvenient, but my only complaint about it.
