I think most engineers would be irritated with a calculator where you have to go through multiple menus to get to the function you need. Sometimes all the new “whistles and bells” are just a distraction. They may be cool for students but most engineers wouldn’t appreciate it.

I agree. CW is the worst update for a Casio calculator. My first impression two months ago is that the CW model is very inefficient on keystrokes. I think they wanted to mimic the operation of higher graphing models, but on graphing calculators it is natural that they have to press more keys because there are so many functions. Finally someone said it in a video! The keyboard layout is noticeably worse.

Maybe the others (students, engineers, etc.) Rather, I find it quite straightforward. All it takes is just going through some of my own calculations and following my instincts. Nice feature is back/undo so I can return to where I was before and just make another keystroke if I goofed up. Yeah, read the manual first.

I agree with you about how annoying it is that they buried everything in menus. The best thing about a scientific calculator is that everything is right there on the keyboard, easy to find. They should have at least given us the option to just hit a number to select an item from the list OR scroll to it and press ok. That would be slightly less annoying. I will say, I have the fx-991cw too and I ran those integrals on mine...and got the exact form 2pi and 7pi rather than the decimal approximation you were mentioning. I do wonder if your settings were different or something. I have my settings to MathI/MathO and it gives exact form. I think the fx-991cw is geared toward high school students now. It seems a little better for those students taking statistics, for instance. On the CW the data they enter does not get erased if they go to a different mode or even if they turn it off and back on, data is still there. I've also noticed that there is persistent memory for matrices, those stay too. And I do like the new feature to define functions f(x) and g(x) so that you can use that in your calculations in the calc mode. I find it very doubtful that CASIO will come back out with the formerly loved fx-991ex model. BUT, I wonder if they are going to improve the fx-115 es plus 2 to fill this gap. Take the 115, make the operating system less clunky, improve it's capabilities so that it can perform 4x4 matrix operations and solve polynomials to degree 4, and leave all of those key shortcuts that engineers and mathematicians love. (And leave rref on there!) This would be the route I'd love to see them go.

Two little things that I've noticed the new CW adds which were not present in the EX are these: 1. The Format menu includes the factored option when the result was an integer. Example: press 420, EXE, Format, Prime factoring and the screen will show 2^3 x 3 x 5 x 7. 2. Shift, Ans is Pre-Ans (which for some reason I don't see in this video). That's a usefull addition: Ans is the last computed result; Pre-Ans is the next to last.

That is true, but I do not think the addition of those functions offsets the annoyance all the additional key presses required on the CW.

Just today I bought FX 991 CW Calculator and I would say it's not bad and it's actually really good. I know there are a lot of keystrokes involved but it makes it easier for beginners to use the calculator because they can actually see what the calculator would do next. Let me clear you, my CW calculator gives answers in fractions and pi too(example: 2 pi), hence that point is no more of concern now. Further more, CW can cost you cheaper than EX one atleast it is cheaper in my country. Another reason to buy CW is that EX is not available anymore and hardly any store owner sells it anymore. I am not being biased for CW, but these are my own thoughts for it. Thank you

The 991EX is near perfection, except I really wish they would give the engineering symbols under Shift function on the numbers like they do on the 991MS (which is my second favourite). In electronical engineering, we use those symbols endlessly so to leave the shift-layer blank instead of using them is an annoying omission. The CW looks like you really have to learn to press many buttons. I never really needed very advanced functions from my calculators during my degree, but being able to input complicated evaluations with perfect accuracy, and quickly under pressure, is most important.

Well, no entirely true. The 991CW does offer some improved features, but overall, the loss of features makes it worse than the 991EX. For example, on 991cw you don't lose your spreadsheet data when changing modes, you also don't lose your stat data. f(x) and g(x) can now be used outside of the table function (in the solver for example). f(x) and g(x) are not lost when switching modes. However, the biggest downside tot he 991CW is the loss of "CALC" and the ":" which allowed for mini programs to be made. The 991CW also increases the number of key strokes for similar operations as compared to the 991EX. So depending on what you need and want, either one good offer a benefit or a disadvantage.

THIS VIDEO CONVEYS FALSE INFORMATION!! THE fx-991CW DISPLAYS EXACT ANSWERS IN THE SAME CIRCUMSTANCES AND THE FORMAT KEY WILL CHANGE FROM 7π TO DECIMAL IN YOUR EXAMPLE. The video makes no mention of the new, highly useful 'Define function'' facility, present on the CW model but absent on the fx-991EX. Furthermore, the sliding of the newer model is more scratch resistant and buttons feel more positive in use, especially the cursor arrow keys which feel wobbly on the EX and look cheap being plastic painted silver to resemble metal. The fx-991CW is thinner and therefore less bulky. False information about the fx-991EX may well be responsible for inflating the price of it to an absurd degree that beggars belief, and helping to promote the sale of counterfeit copies which look the same but use fault motherboards and can't perform some calculations that the genuine item can. The fx-991CW is much better took.

I agree that Casio has made a backwards step with the new CW model. Yes its got some extras like higher res screen, but why on earth make the user go through layers of menus to get to a function? In an exam situation where every second counts adding unnecessary extra key strokes matters. Also users have got use to the classic key layout which works from model to model and means there is less learning. I don't see how introducing round keys and re-arranging the layout helps users.

But all I can see is that the ex is much worse because its not straight forward and transparent like the CW. Additionally when calculating the integral, I get 2π so you must have set to MathI/DecimalO instead of MathI/MathO. Instead of saying that in your opinion its bad, you just say its bad in the first few seconds.

I jave both of them, to make a decision, I would see what kind of questions are expected in given subject exam and thereby act accordingly. The irritating part of CW is the need to scroll to menu in order to switch between decimal & fraction. Whereas EX does this with press of single button.

I came to know that it's called sequential execution and 991-cw doesn't have it for some reason. An alternative to this feature is to use table. Table allows to compute two functions f(x) and g(x) simultaneously and if you happen to have two expression to solve in sequence you can just define those two expressions for f(x) and g(x) respectively and the calculator will perform the execution for you. Although it may seem like f(x) and g(x) 's definition expression requires to be in the form of 'x' variable, it is not. You can just put an expression with any number of unknown variables with or without 'x' and it will compute value for you as long as those variables have been assigned their value from variable section. There is a dedicated key for assigning values to the variable. If you don't assign any value than any garbage value will be assigned. But I'm sure you will require them to be assigned as you will be doing Numerical Method's problem where at each step the values will change or update. So, to conclude: Step 1: You go to table mode. Step 2: You define f(x) with expresssion 1 and and g(x) with expression 2. Step 3: You assign initial values of each variable that has been used in expression 1 and 2. Step 4: You press execute button so it will compute value for f(x) and g(x) and put them in the respective column. Step 5: You note that value in you paper. Step 6: You update the values of the variables used in expression 1 and 2 as required. Step 7: You press execute again and new output will be put in second row in their respective column and you note them and update the variable's as necessary and continue the process until you get desired result. I have used this approach to solve Bisection method, Secant method, Regula-Falsi method in Numerical Method subject. In the above mentioned methods you don't have to deal with more than two expressions. This approach can be used with any method if you can simplify those methods into requiring only two expressions. It may sound ridiculously complex, but believe me if you master this calculator you can perform the above mentioned Numerical Method problems in just half of the time compared to the old 991-ex because the 991-cw version is faster(in computation) and more convenient to use too because of its friendly interface, although some might still debate on favor of 991-ex's interface but that's only because they are used to it and switching to new interface requires some time to get familiar with, which I agree. But when you master it, you can't be beaten in any form by 991-ex's users. I dared myself to bring 991-cw in the exam hall just to prove this point to myself and I performed faster than my classmates. But since you can only execute two expressions simultaneously, I still use 991-ex for more than two expressions. I hate engineers at Casio for removing useful feature at the same time I also love 991-cw because of its fast computation. It is like the super computer of the calculators.

But that's slower than a direct exponential function, and I don't mean slower to type in, but slower to compute. Try, for example, the integral of e raised to the x² from 5 to 10 and in the EX you'll see the difference in execution time. Does anybody know where the direct exponential function is in the CW, if it's there and I haven't found it? It used to be Shift ln in the EX.

The CW did give the correct answers for the integrals in the Speed of Calculation section of your video. The reason you received the decimal results is because you did not select MathI/MathO setting for the Input/Output on the CW. If you would have selected that setting, the symbolic results would have appeared on the CW. I am surprised that for as much as you know about both calculators, you neglected to make the correct input/output setting. Shame shame!

Good thing Casio calculators last for a long time. I bought two of the 991ex because I heard that it is already discontinued and I'm pretty sure that these will last me a lifetime like my casio 82es plus AU that had been given to me by my cousin in Australia making the calculator 7+ years old. My family is already filled with crazy folks risking me as well due to my genes and I'm gonna make that these calculator wouldn't contribute as an another factor. Btw, whoever thought of these relayout deserves to be fired and be tormented by Satan himself.

The price for the 991ex is extremely high, ranging from 50 to 80 euros due to its popularity, and it is sold out everywhere. However, that's not the case for the 991cw, even though it's practically the same. The price for this model is around 30 euros, and it is relatively unknown, making it easy and affordable to obtain.

My German model (DE CW) does solve the integrals with the exact result. However, I do not believe that for an educational tool it's bad to display a multi-digit approximate result for a numerical approximation. I would prefer to school my students to recognize some (more) numbers from the decimal approximation, and also learn that this a numerical approach that may not give the exact result. Besides, the EX dropped out of exact result at almost arbitrary thresholds.

991 EX DE (and the japanese one, with a complicated name) have more functions than the standard 991 EX, these including Pre ans, gcd and lcm. Actually, they make the 991 EX like the 115 (which is still the most complete casio calc). I don't know and don't like this kind of downgrade for the general western market made by casio. The New CW in my opinion is KIND of similar to the Texas Instruments TI 30 Pro/36 Pro... with the big difference that is not a TI. So they made a medley that is nor one nor the other. I LOVE Texas scientific calcs... they are more similar to my thinking, so I can do things even if i do not remember the pattern to achieve them. BUT Casio had its strenghts, more buttons and less menus, which was nice for angles and roots, and the ENG reverse button, fact button, (and gcd, lcm... with a DE EX). Now these strenghts are lost. It can be a good calculator for school, with a tool like the Disequalities analysis... but in my opinion it is a complete mess for someone who need it to work. The difference between casio and TI was good. Now there is TI that is completely stuck and don't innovate (having a QR code or the inequality analyst, or a "personal menu with the most used functions would be great) and Casio that for unknown reasons decided to copy TI... without being TI. Who knows why.

Agree. They simply added the word "app" for no added benefit. They might have assuemd if people hear the word "app" they would assume the calcualtor is more functional. in face it is so dumb that I hate it. I hope they continue with the original Caso style. Simple buttons and no deep menues.

It's a very good calculator. I think it's more user-friendly, in my opinion. Plus, it retains it's answers unlike Casio calculator even when powdered down. So that gives it a distinct advantage over the Casio. But there are always pros and cons to every device. The reality is that you can't go wrong with either calculator. But if you're in the United States, the Texas Intruments calculators are always recommended over the Casio units because schools in the U.S. almost always use Texas Instruments exclusively, and that's what your professor/teacher is going to be used to using. Often, Casio calculators are not allowed because Texas Intruments is preferred by United States schools and universities. But if you are in the EU, then Casio is usually more popular. I would very much ask your teacher or professor what they would recommend before you buy. Sometimes, a teacher or professor will want a specific calculator for a specific function that it may have for the type of math that you'll be learning. And often they don't want you buying a calculator that it to powerful for the tasks since the calculator may end up doing all the work to well and give you the answers without learning it in your head. So this is why calculators like a Texas Intruments Ti-89 or TI-Nspire are almost never allowed in some cases since these calculators have CAS and can do all the problem solving for you and can give exact answers all the time. So TLDR ask your teacher what they recommend. Because if you buy one too powerful or one that the teacher may not be familiar with, they may say you can't use it. 🙂

What the hell made casio think removing the alpha button would be a good idea, the catalog menu is irritating as hell, and why tf the "ans" is so far away from the equal button, and who the fk throught replacing "=" into "exe" would be a good idea. And the worst part of it is that casio is not producing the old model anymore, so If I lose my preciate easy to use calcultor I will be fucked off.

The "upgraded" product looks like art/design people applying "idiot-oriented" design on scientific calculators. I think designers do not even know how to use engineering/scientific calculators, and they assume everyone is unable to use those calculator as themselves. Such a design may be suitable for financial or daily calculators, but high-end scientific calculators should not hide everything in the menu and should not forget to consider typing efficiency.

I've been using their calculator since the ES series. I've intensively used multiple versions of the CW series, including 8200AU, 999, jp900, and 570. 1. They hide everything (calculus, probability, complex symbols, etc.) in the menu to reduce manufacturing costs (all models have the same key and same shift functions) 2. Removed using number keys to select options and modes, wasting time using page up/down and arrows to navigate their menu. 3. The S-D key is gone, and it's unable to switch between fractions and decimals quickly 4. Newtown solve is no longer available in basic calculations; Thus, it takes extra time, and it's no longer competitive with opening Maple/Matlab/Mathematica to do things. The 'improved' things you've mentioned are trade-offs to compensate the removed easy way of storing value in variables, "CALC" and multi-statement for iteration. I'll be happier if they upgrade the chip, add more functions, and increase calculation speed and accuracy but keep the keypad the same layout as previous generations in the past 10+ years. (This does not apply to custom versions in some countries. Those models have both features of the previous generation and new features and put more functions in shift keys than global versions)
