![]() ![]() There is a German version known as the FX-991DEX that is available from Europe. For everyone else, I highly recommend this calculator for it's ease of use and sheer functionality.Īlso of note to those considering this model: The calculator doesn't have RPN (Reverse Polish Notation), so if that is something that is important to you, condsider buying an HP instead. While this is not a CAS (Computer Algebraic System) calculator, it is very capable of solving simu ltaneous equations, working with complex numbers, and handling matrix and vector math.Ĭompared to the FX-115ES that I had before, the FX-991EX is several times faster, so they have upgraded the processor on this one, yet it is still able to run off solar power when needed. ![]() Each mode (matrix, vector, statistics, etc.) has its own contextual features which are found in a menu displayed with the options button (OPTN).Įquations can be entered just like you would in a textbook, including integrals, derivatives, summations, proper and improper fractions, and more. The most used functions are the most accessible with a single button press, followed by slightly lesser used functions using the SHIFT key. If you've used the FX-300 / FX-115 ES or ES+ models before, you should feel right at home. I've owned quite a few different calculators over the years and have found that the Casio models in particular are very easy to use. Intuitive interface, crisp display, and solar powered too! :-) The best non-graphing calculator I've seen yet.
