5.0 out of 5 stars Solid, durable, easy to use
This calculator is great and easy to use. Lots of functions. There are lots of tutorials on YouTube and can be a little complex, but also once you use it a few times you get the hang of it. Good quality for the money. The display is a little small and only has the two lines, but you can scroll up with arrows

5.0 out of 5 stars Great features, visibility not the best
This is a first impression, as I learn more, I'll add info.I chose this calculator because I needed more memories/variables for storing often-used constants for chemistry courses. It gives you the following memory/variables for quick recall/use: A,B,C,D,E,F,X,Y,M, looks like 9 memories. There are also 40 built-in scientific constants which are less easy to retrieve (shift,const then 01, 02, etc.) but might be handy (of course you can save selected ones in the memory/variables for easier access).Visibility is always an issue with calculators, both keypad glare and screen angle. Compared to a very basic TI-30Xa calculator, the Casio screen is less readable because the digits are smaller and much less contrast (blue on bluish screen vs black on white/gray for TI). As with most reflective LCD screens, including the TI, you have to get the light angle just right for maximum viewing. This is a significant problem I find because lighting varies a lot in different places. Under exam pressure, you can't afford to misread, but it can happen too easily with these screens. But the TI is easier to read - however, it is just a one-number at a time display. The Casio shows your whole formula as you type it, so for that feature you pay a price with less clarity. With the Casio, if I get the light angle best for the display, I tend to get glare on the buttons. The TI has the same issue, but the buttons are bigger and bolder and black/white, so more readable.I chose the white model Casio to see if somehow it is clearer. The numeric pad is white on gray buttons, which is pretty, but not as readable as white on black for sure. I may get the black model to see if that is clearer (actually not sure a black model is available for this exact version).My eyesight is not perfect, so this may be a non-issue for you, especially young people. I just find that the number of hours spent calculating and reading small text is a factor, so I'm trying to optimize eye strain to a minimum and evaluate study tools in that context.Otherwise, I think this Casio fx-115ES Plus is packed with a ton of powerful features and is a great value from that standpoint.Update 9/9/2022 - a feature I miss on this calculator is the "change sign" button, which flips the result from positive to negative or vice-versa. You can multiply by -1, but it feels cumbersome. Because this calculator enters whole expressions instead of one-number-per-operation like simple calculators, you may not have as much need for the "change sign" function. For me, it is natural and I often like to see partial results as I go. So if the calculation is for example: 66 / (1 - (grams / molar mass)), it is natural for me to first calculate grams / molar mass (showing me the moles of a substance), then "Change Sign" and add 1, then invert the answer and X 66. So "change sign" and "invert" go hand-in-hand for doing a computation "from the inside out" with minimum parentheses. It is also a useful skill in case you find yourself with a simple calculator on occasion. The Casio has the (-) key, but as yet I haven't found it more useful than the minus key. Maybe someone can explain it, the manual doesn't elaborate.Update: somehow I missed the "Ans" button next to the "=" key. So not a single button push, but the "-" button followed by the "Ans" button will invert the sign of your answer and you can proceed from there. Also, the Ans button is needed for taking a function of your last answer, such as log(), etc. (unlike simpler calculators where log always takes log of last calculation). And "alpha" "Ans" will get you the "pre-answer", the answer before the last answer. So there is a two-memory stack at work for the answers.Update: another real weakness of this calculator is there is no (that I know of) quick way to change from fixed point to scientific notation. This is standard on many very basic scientific calculators. You can go through a cumbersome mode shift with shift keys, selecting precision, yada, but a single dedicated key is what is needed. If you have .00612 and want to quickly see it as 6.12x10^-3 or vice versa -- forget it. I think that is a serious omission, and hopefully there is another brand out there with that useful key for my next calcluator. Too bad.
5.0 out of 5 stars Much recommended, very happy with it
I initially got the fx-991ES (because the lower number of this one made me assume it had less capability) but actually this is the U.S. version of the 991ES and it is slightly more capable. The 991ES is the international version, and Casio is preferred in education outside of the U.S. (here, TI is used most), so maybe some abilities are removed from the 991ES to satisfy educator requests (I don't recall what these are and too lazy to check, but essentially these two calculators are the same, the differences are super minor). I do like the looks of the black version better, but both of them look nice. I got this one as a "spare" and so I always have one nearby to grab, because I like it so much. Plus I'm worried that its days are numbered because Casio seems to be moving to a menu-based version with less printing on and above the keys, and I prefer to just learn the keys for quick access. I got interested in these calculators (initially the 991ES) because there are nice Android calculator apps that are meant to mimic these, and I wanted the real thing. If you are interested in this calculator, my impression is the 991ES has more useful reviews (I wrote one for that too), so maybe look there to get a more serious review than this one and others that just say "it's great." I'll just say it is super at symbolic math (fractions, square roots etc) and very fast and convenient to to use for that. I have no complaints about this calculator and strongly recommend it.
Superb
Works fine, is cute, really fast.
Buena calidad
Llevó casi dos años con la calculadora y jamás ha fallado. Valió la pena la compra.
Produto excelente!
Bom, inicialmente fui procurar o número de funções que tem a calculadora, deu um trabalhinho para eu encontrar e vi que eram 460 ao todo. Ela é bem completa: realiza cálculos com equações, inequações, matriz até 3x3, vetores, integrais e derivadas definidas, função Solve, função verificar, distribuição, base-n, números complexos, MMC e MDC, constantes científicas e conversões métricas, e por aí vai. Tem uma gama de funcionalidades, e é bem em conta pelo que ela proporciona. Muito útil em diversos tipos de operações, desde as mais simples as mais complexas, por fim, é uma calculadora excelente e muito completa.
Great calculator
Used for my maths and physics exam. Good and easy to use
Great and neat looking
It’s advanced and very neat looking, works well!
