Review: BEST CALCULATOR FOR ITS MONEY. WORKS ON INTEGRALS - THIS CALC IS AMAZING. for the price it is the best calculator at its price point without a doubt. I had always used Texas Instruments as they were always pushed in the schools. But this calculator is way better. This calculator can do everything a ti30 can do and more. It does derivatives and it works extremely well. You can get the value of an integral with this. You can use it for literally anything (up to calculus I and some of calculus II). If you don't want to spend a bunch of money for a calculator and wont be taking any crazy MATH classes, this is definitely the calculator to get. it is suitable in almost all normal math classes and the display is good enough. The display isn't crazy bright or anything but its less than 20 bucks so as long as you are in a lit room you should be fine.
Review: 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.

## Questions & Answers

**Q: Why does the calculator not display decimal answers and only fractions, and why won't it square numbers that aren't perfect squares**
A: Hello, the sd key will change fractions to decimals and back if needed. 
The calculator will simplify square roots that are not perfect squares and if you need a decimal answer then press the sd key and if will convert it to a decimal.

**Q: Is there a comma separator - thousands function for millions and billions,etc. for example 50,000,000,000?**
A: This is not a business calculator - not sure why you'd want a comma separator when you'd be using scientific notation: 5x10^10 for example.

**Q: How is this different than the fx-300ESPLUS2 ?**
A: I am not familiar with the fx-300ESPLU52. You might be able to go to the Casio website to get information on how they are different. This one (the fx-115) has many features which I have not yet used.

**Q: can it used in SAT exam?**
A: I'm a retired hs teacher. I've bought this model two times for my own kids because it met their needs and can be used during standardized exams such as the SAT.

### ⭐⭐⭐⭐⭐ My fav calculator so far- and its cute
*by H***P on October 27, 2025*

The Casio fx-115ES Plus 2nd Edition is an excellent calculator and definitely worth the purchase if you’re a student or someone who works with math or science regularly. It feels solid and well-built, with responsive buttons that make typing fast and accurate. The Display is a huge plus because it shows fractions, roots, and equations exactly how they look in a textbook, which makes checking your work much easier. I’ve used it for calculus, physics, and statistics, and it handles all the functions I need with no issues. The menu layout is intuitive once you get used to it, and the battery life seems great so far. Overall, it’s reliable, easy to use, and perfect for both school and professional use. I'd say its a must-have for anyone serious about math or science.
