Para calcular la calificación general por estrellas y el desglose porcentual por estrellas, no usamos un promedio simple. Nuestro sistema toma en cuenta cosas como lo reciente que es una calificación y si el revisor compró el producto en Amazon. También analiza las calificaciones para verificar su fiabilidad.
Best calculator for students who can't use a graphing calculator in their class. Lots of functions and has a "Math" mode that allows doing operations with fractions and gives answers in fractions. Spend the time to read the manual and you'll see how awesome this calculator really is. Small and light enough to carry around to all your classes!
nice lay out and user friendly. cover goes on and off easily. Key pressure is nice. I like the design because it is not overly fancy and space age looking like the others. Read out is very clear. I like the way the function keys are arranged. Feels like good quality.
Amazing calculator in terms of capabilities and packaging. If you need a calculator with a wide range of capabilities without programing, this may be the one for you. I definitely like the cover for it. Personally, I would have liked 3-4 statistical distributions rather than some of the more obscure mathematical capabilities. The manual is not a plus: (1) formatted to a size that approximates wallet photos [deliberately I think]; (2) can't carry with the calculator regardless of what the manufacturer suggests - too thick; (3) having an electronic version formatted for a smart phone would be great.
