There is only a sheet of instructions instead of a booklet. The instructions are pretty small print. However, there are plenty of tutorials and downloadable instructions on the internet.This is a very powerful calculator. It does about everything short of graphing. Worth the money.

When it comes to calculators, the name Casio is synonymous. I grew up with using Casio in school for my home and coursework. It has been a while since I have used a scientific calculator.After several options, I chose the Casio FX-115ESPLUS2 Scientific Calculator, Natural Textbook Display. This is a calculator that my oldest daughter will be using when the time comes for her to need an advanced tool for math. As of right now, I am using the Casio Calculator for budgeting and bills.The calculator its self comes with a cover that slides off to protect the device. The calculator is essentially the same size of my Galaxy 10+ phone to give a good representation of size.*****I did receive this product for free in exchange for my honest opinion.*****

I've always preferred Casio calculators over Texas Instruments, and now my kids do, too. We originally had one scientific calculator for my son, then my daughter "borrowed" it when she went into Algebra I. Needless to say, this is a replacement for my son as he heads into Trig. Both of my kids like the layout of the function keys and find it intuitive to use, and the white with gray/green is a refreshing change to the dark colors of the original.

I have used Casio products for the past 20+ years and I recently need to get a scientific calculator for my daughter for her advanced classes. I picked up The Casio FX-115ES PLUS 2 scientific calculator and I was very impressed with its capabilities. This calculator is solar-plus-battery powered and has a large Textbook display. My past experience with Casio’s solar technology is very good and in a well lighted room the solar cell provides enough energy to extend the battery life. The Casio FX-115ES PLUS 2 scientific calculator is pretty advance. It can perform advance Statistics, Matrix, Conversion functions, General Math, Pre-Algebra, Algebra I & II, Geometry, Trigonometry, Statistics, Calculus, Chemistry, and complex Engineering equations.

I've had this calculator for the majority of my Engineering education. Its a great calculator for the price. Feels hollow and plasticy, but aside from this minor complaint, it works amazing for upper-level university courses, up until more complex stuff where a graphing or CAS calculator is better suited for the task. Complex math, equation solver, and easy input of difficult formulas. Other reviews mention fractions, but the S<=>D button solves this if you would rather see the decimal equivalent. 10/10 would reccomend.
It is true that the Casio fx-115ES Plus, 2nd edition is powerful and has many functions, but the construction of the calculator itself is the cheapest plastic. It is very light and flimsy, like it came from the dollar store. Also, with the calculator being a white background, the keys are harder to read. The 1st edition of this calculator was far superior, with quality workmanship and grey background so the keys were easier to read. They should not have taken the 1st edition out of production. Casio worsened many of their models by making these 2nd editions, and I will not hold my peace on the matter. Spend a few more dollars and get a sturdier unit from Texas Instruments, such as the TI-30XIIS.Do not depend on the other reviews for this product since they were ... MoreIt is true that the Casio fx-115ES Plus, 2nd edition is powerful and has many functions, but the construction of the calculator itself is the cheapest plastic.

I received the following item from the Spark Reviewer program and was asked to provide an unbiased product review. The Casio FX-115ESPLUS2 Scientific Calculator is an impressive mathematical tool. This calculator is packed with features. I will be honest in that I chose this item for my daughter, who will be a Junior in high school this year. She performed many calculations on it using the Algebra and Geometry features. She told me it is similar to the device the school supplies…however, this has more features and hasn’t been abused. I have a friend who works as an Engineer, he stated it would perform well in his daily activities. I used it to perform general calculations, Algebra and conversions. This device goes wayyy beyond my capabilities. The screen allows you ... MoreI received the following item from the Spark Reviewer program and was asked to provide an unbiased product review.

I have a friend who works as an Engineer, he stated it would perform well in his daily activities. I used it to perform general calculations, Algebra and conversions. This device goes wayyy beyond my capabilities. The screen allows you to enter the problems/equations as they appear in the textbook. This is nice because it reassures that you have entered it correctly using the keypad. The calculator is very slim, less than ½ “, and is approximately 6”L x 3”W. The device has a hard plastic slide-on protective cover. This item is powered using a solar panel and also has a battery backup installed. The included startup guide is well written with easy step by step instructions on performing the many features. I would definitely recommend this Casio Scientific Calculator to anyone seeking a well-designed and feature packed mathematical tool.
This calculator is pretty amazing. It allows you to type in the formula as is and calculate the answer. As a student, this is awesome. From a teacher perspective, it could cause a student to avoid learning the steps for solving certain equations. Overall though, very handy to check my own work!
I had an old Casio calculator with a similar model number in the 90s. The new version is not the same. The natural textbook display is an improvement.However, some of the keys are oddly laid out and don't have the same functions as the old calculators. For example, to turn the calculator off you have to press Shift+AC rather than the on button. Pi is not a dedicated button, but is a Shift+10x button.The old calculators had a 10^3 button which was convenient for adding thousands. This has a 10^x button, so you would have to press 10^x then 3 to do the same function.Finally, the negative button is not the same as in the past. You have to enter negative first and then the number. On the old 90s calculators you could enter the number then the negative. Probably ... MoreI had an old Casio calculator with a similar model number in the 90s. The new version is not the same.

Probably not a big deal to most people, but I find that annoying with TI calculators, and I thought this Casio would be similar in function to the old one I had.If you are using this because it say it can do matrix algebra - be warned it can only do a 3X3 matrix.
I've owned quite a few different calculators over the years and have found that the Casio models in particular are very easy to use. The Classwiz FX-991EX is no exception. If you've used the FX-300 / FX-115 ES or ES+ models before, you should feel right at home. The most used functions are the most accessible with a single button press, followed by slightly lesser used functions using the SHIFT key. Each mode (matrix, vector, statistics, etc.) has its own contextual features which are found in a menu displayed with the options button (OPTN). Equations can be entered just like you would in a textbook, including integrals, derivatives, summations, proper and improper fractions, and more. While this is not a CAS (Computer Algebraic System) calculator, it is very ... MoreI've owned quite a few different calculators over the years and have found that the Casio models in particular are very easy to use.

While this is not a CAS (Computer Algebraic System) calculator, it is very capable of solving simultaneous equations, working with complex numbers, and handling matrix and vector math. Compared to the FX-115ES that I had before, the FX-991EX is several times faster, so they have upgraded the processor on this one, yet it is still able to run off solar power when needed. The calculator doesn't have RPN (Reverse Polish Notation), so if that is something that is important to you, condsider buying an HP instead. For everyone else, I highly recommend this calculator for it's ease of use and sheer functionality. Also of note to those considering this model: There is a German version known as the FX-991DEX that is available from Europe. It has added functions that I've heard were removed from the US version so that the calculator would be allowed for certain curriculum / exams. According to the Casio International website, the FX-991EX has 552 functions and the Casio Europe website shows the FX-991DEX version as having 696 functions. All in all an great calculator for very little money with the nicest display I've seen yet on a solar powered calculator.
