Kind of a stupid question, but I don't have much experience with calculators and thought some of you might.
I'm sitting an exam and would like to use my calculator, in particular this one: http://www.casio-europe.com/euro/sc/technical/fx82sxplus/
The only text I've had from the school is this: "A hand held calculator may be used when answering questions on this paper but it must not be pre-programmed or able to display graphics, text or algebraic equations."
As far as I can tell I should be fine, right?
With these types of questions, I would always ask my teacher/school exactly which model of calculator is OK to use. I would do this since even most teachers have no idea of what a specific calculator can or can't do. So even if you ask them to take a look at your specific calculator, they might not able to verify that it is appropriate for use.
That said, when talk is about calculators that are programmable and can show graphics I think most people usually think about calculators where you can graph functions like the Texas Instrument TI-84. This HP calculator apparently will accept SD memory cards in some way. These calculators will usually also hold notes in some way.
From the looks of it, the calculator that you are considering does nothing in terms of graphing or storing notes or manipulating algebraic equations. The only thing your calculator might be able to store is numbers.
