I can already anticipate some calculators, previously liked to CASIO best. And I would always opt for a CASIO. I bought it because of the color, but even for me, the calculator has been competitive sports, to understand this at all. Meanwhile, I get along well with it, have got used to me in the UK area to arithmetic and convert the DE area. The guide helps basically for the initial functions to at least set the basic structure and functions as DE RAD ect. adjust. But otherwise you is that with the help of internet. ;)
Visually, the calculator is really something for girls. Notice there is a UK format, no DE, the hot rethink and think. Also modify the results of fracture in decimals, was difficult to understand, but really it's just a button press. * ENG * button!
