I’m a high school math teacher with 20+ years of experience and have used nearly every graphing calculator model out there since the TI-81. This Casio model wouldn’t be my first personal choice or recommendation to families, but it has definite strengths and it’s an unbeatable value for the price.Compared to the ubiquitous TI-84, the Casio has better home screen functionality. It reports fractions, simplified roots, special trig ratios, etc. as exact values instead of decimal approximations. You can bring up a fraction template or switch between exact and approximate values with a single button press. The keys are large and have nice action and a sensible layout. The calculator is very powerful and easy to use on the home screen. And – to be fair – that’s where students spend much of their time on a calculator in math and science classes. You can also download a free CAS package to provide symbolic solving, simplification, differentiation, etc. for upper-level HS or university courses. That’s a tremendous value for the price!However, I’ve always found Casio’s menu system clunky when it comes to graphs, tables, stats calculations, etc. and this model is no exception. The relatively low res screen doesn’t do this model any favors for usability either. Anything that’s not a home screen calculation seems to take an extra couple keystrokes compared to a TI-84 and/or just be more confusing. To take one example, tables of values are generated within a finite range that can only be modified explicitly. So if you generate a table for a function, you get values for x=-20 to x=20 by default. You can’t just scroll up or down to see more values outside that range without trekking back through the menus to the table settings, which are themselves much harder to find than on a TI. This is quite awkward for students that haven’t yet developed a sense for what part of the domain they want to examine! Clumsy UI choices like this abound.If money were not a consideration, I’d still hesitantly recommend a TI-84 Plus CE over this model for typical students. The TI is weaker on the home screen, but the higher screen resolution, simpler menus, and wide availability of help/tutorials make it easier for students to use on balance. Now… is a TI-84 Plus CE worth more twice the price of this Casio? Maybe not. If money is tight, this is a terrific choice. It can certainly do everything an 84 can do and more, just maybe with a bit more effort. However, the HP Prime (at the same cost as a TI-84) is a far more powerful and usable calculator than either this Casio or the TI-84 – the Prime is my personal favorite calculator and the model I’d recommend for students pursuing STEM paths that require calculus and post-calculus mathematics.Outside of educational settings, this Casio model would also be a fine budget choice for hobbyists or professionals that might occasionally want graphing, stats, or programming capabilities but that don’t need something as full-featured and costly as a Prime or something more specialized like an RPN calculator.Overall, this isn’t my favorite graphing calculator for students. But the value for the dollar is unbeatable if you’re dedicated or experienced enough to deal with its quirks.

For half the price of The ti-84 plus It can do all things that calculator can do and more.Let’s start with the design, I really like the design of this calculator. It’s minimalistic, simple, not too distracting but still ha some flair. I like the rose pattern on the back it gives it a nice touch that stands out from other calculators.For a graphing calculator, It’s easy enough to use of course like with all graphing calculators there is a learning curve. You really need to familiarize with all of the buttons in order to use the calculator properly. I had to look up a lot of YouTube tutorials to get the feel of how the buttons work.That being said if you do know how to fully use this calculator is very useful. There is a bunch of menus with a lot of features. The notetaking feature is the one I normally use the most. It’s really helpful keeping mathematical equations and formulas for reference later. It really helped me a lot but it comes to test taking. The thing i hate about Texas instruments calculator is when I type in 2xπ, it would just give me 2π without an option to see the decimal answer. This really irritated me as it was something I could’ve easily guessed without a calculator. However with the Casio calculator when I type in the same equation, it gives me a choice to see the decimal answer along side with 2π. In a lot of situations involving pi, this could make or break a problem. I am very glad that Casio allows you to see both answers.It’s very good value for money. Like I said for half the price of the ti-84 plus, the Casio can do exactly the same things that calculator can do and then some. Great value for money. It’s pretty concerning that Texas instruments has been the the standard calculator in schools and colleges and is required in a lot of classes. Not a lot of people can shell out double the price for the calculator. I hope to see casio being used more in American schools as we need more choice and competition as clearly lack there of.

This calculator definitely has a lot of functionality-probably more than I need. I’m disappointed in the screen display, though. The Casio education site where I first saw it said it had a backlight but it doesn’t. The screenshots in the pictures are a lot brighter than the actual screen on the calculator. If you’ve got really good lighting it’s ok but if not it’s very difficult to see, especially the tabs at the bottom of the screen.

I’m an old guy, an amateur astronomer. I don’t use this machine academically, so I have no comment to make about that. In the past, I’ve used a Canon F-300P (terrible), a Sharp EL-5500II (always loved it, still do) and an HP-48G (good but short-lived). I also have a CASIO fx-115 ES PLUS, which is a terrific basic (solar-powered, non-programmable) scientific calculator.I use the fx-9750GIII to run numerical programs (astronomy, calendar, n-point interpolation, polynomial fits) using Casio BASIC. For that purpose, it’s very fast and accurate, with 15-decimal precision. I only wish that all fifteen decimals could be displayed at once. (This is a perpetual gripe of mine. Why not give the user this ability?????) HP’s normally have only 12 decimals, but all twelve may be shown at once.Programs and data are easily saved to one’s computer using a standard USB 2.0 A to mini-B cable, which is NOT included. This is a bare-bones package. One will need to download documentation and upgrades from the CASIO website. I easily upgraded the OS to version 3.50 from 3.40. Documentation is okay — in pdf form only, of course. Battery life is still a mystery (I just got the thing). Overall, for 45$ or so, it seems to have been a good buy. Some users may need to buy a cable to go with.

Excelente
Calidad precio practicidad estupenda. La simple cosa que se autoguarden los datos, apagar y encender y que sigan ahi lo vale. Muy práctica, incluye una hoja de calculo letra un poco pequeña pero util. Sin explorar todas las opciones aun pero es un equipo genial. Memorias de la A a la Z, copiar linea, pegar en modo calculadora simple hace eficiente el trabajo repetitivo y mas. Excelente producto en termino de mediano a avanzado. Algunas funciones algo rebuscadas para accederlas pero cuestión de acostumbrarse nada mas. Las baterías duraron unos meses menos del año, quizas es normal pero si se le dio uso constante. Su otro modelo identico avanzado a color tiene teclas muy sensibles. Este modelo mas austero estan perfectas para uso de campo.

Muy poderosa
Calculadora-graficadora MUY poderosa y fácil de usar, sin duda no le pide nada a la TI-84 plus, con razón en el empaque dice que la compares con la TI (que en lo personal son muy complicadas de usar y más costosas).Pero bueno dejare los beneficios y funciones que quizá no digan en los manuales o videos de internet ya que esta calculadora es de las más nuevas la Casio fx-9750GIII, además de mi experiencia desde el punto de vista de un alumno de ingeniería eléctrica en etapa terminal (cursando último semestre).Anteriormente usaba la calculadora Casio FX-991EX Classwiz, que por cierto es muy buena, pero a estas alturas de la carrera necesitaba algo un poco más, lo que se hablara a continuación.Razones por las cuales compre esta calculadora, no tanto por ser graficadora, más que nada por*Puede almacenar hasta 28 variables, todas las letras del alfabeto A-Z y además otras variables adicionales “theta” y “r”. Necesitaba forzosamente esto ya que en mi carrera se resuelven mucho sistemas de potencia que incluyen transformadores, maquinas síncronas, motores, etc., y requiero usar todos los decimales en números complejos, por lo que es muuuuuy útil el poder salvar esas cantidades o almacenarlas en hasta 28 variables, y no perder tiempo en volver a escribir el numero (parte real + parte imaginaria) y se obtienen resultados más exactos.*Puede resolver sistemas de ecuaciones lineales de hasta 6 incógnitas y lo mejor es que hasta con números complejos (algo que la classwiz no podía resolver sistemas de ecuaciones con números complejos).*se pueden guardar de la A-Z matrices, desconozco el límite, puse como prueba una matriz de 20×20, pero normalmente en mi carrera resolvemos matrices con números complejos para los buses o nodos de un SEP normalmente de 5×5, que incluyen números complejos.*Puede resolver inversa de matrices, esto es algo que se agradece bastante ya que, en mi caso, la matriz de impedancia de bus es la matriz inversa de la de admitancias, y a veces tenemos que invertir matrices de 6×6, así que si adicionamos el poder almacenar variables es una chulada.y adicional*es programable con Python, que es algo que personalmente no uso, es importante mencionar que se puede conectar a la computadora, pero no incluye el cable, hay que comprarse por separado.*Puede graficar como su nombre lo dice*Resuelve operaciones de estadística, genera números aleatorios y otras funciones, pero desconozco porque no las uso.Desventajas:*Personalmente por lo que uno paga no se puede pedir más, es una muy buena inversión, me hubiera gustado tener esta graficadora desde el inicio de la carrera es un Must have. Pero, sin embargo, algo que si me gustaría que se implementara es que tuviera batería recargable, aunque las baterías que usa (AAAx4) le duran bastante, dice que aproximadamente 1-2 años, pero depende del uso, en mi caso solo la enciendo cuando voy a hacer un cálculo, anoto el resultado y la apago, no es que la deje 10 minutos encendida (me parece que después de 10 minutos se apaga sola para ahorrar batería).
