Love it as an A-Level FM student (won't be upgrading to this one now as the changes to the layout is too drastic) 2:53 - no shortcut is a problem (the most used is Menu -> A -> 2 -> 2 in GCSE lol) No way pi is not a button lol Functions is great but I can just use 'ans' 20:00 - seems like the EX doesn't have inverse binomial as well but it has inverse normal - might need to use a graphing for that
Best way to approach the "format" issue is changing the input/output display to MathI/DecimalO in the calculator settings menu (Config -> Calc. config -> input/output -> MathI/DecimalO). That way you don't have to change the output format every time you get a fraction as the result is always shown in decimal format. The other way is clicking shift-EXE (≈) every time you perform a calculation, which can be a bit annoying being those keys so far apart from each other. My biggest dissapointment with the new CW, besides having so many functions hidden, is the colour palette they chose for the iberian market (fx-991SP CW - white and gold). The contrast between these two colors makes it a bit hard to see the alternative functions...
Yes this is addressed in another video. However it is worth noting that for some exams/course the initial exact answer may be preferred in a higher number of questions, so I guess it is user preference.
Reading some comments made me think that this calculator was harder to use and it made everything more tedious than older models like the 991EX for example, but having the actual calculator in my hands i can realize that everything is not that bad, it just fits more stuff inside a menu and the important stuff is on the outside. I consider this model to be more useful for students as some college/highschool students may find useful the menus to memorize and/or learn the name of most of the functions that weren't named before and they just knew the icon and what it does, and yeah, that may sound like a weak argument but we can leave the menu as a way of taste and availability as i couldn't find the 991 EX in my country but i could find this one faster.
I would have been annoyed by dumbing down a known UI when I was in the middle of an engineering class. Now that I'm working, 99% of work happens on keyboard and monitor, so the couple times a week I pull out a calculator, I'd rather it be intuitive than efficient.
This calculator is available in the U.S. and you can literally buy any of the Casio and Texas Intruments graphing calculators in the U.S. there all avaliable here. Personally I've never had an issue buying any specific model from either company in the U.S.

Yes. Bit the difference is that TI is implemented in a way that is LOGICAL and FAST, for example, with the multi- keys functions. It is different, but fast. Here it seems they kept the "Casio mind-set", but changed to a "TI design" and in my opinion it doesn't work. More: the nice thing was having and wotking with both TI AND CASIO, because each one was the best at a particular thing...
It appears as if this calculator allows one to define a function, and use it in calculations and solve as f(x), instead of having to rewrite the equation every time one wished to use the function that one has defined. It appears that one could choose the integration template and insert f(x) instead of rewriting the equation that was saved into f(x) for example…this is a notable improvement. I wonder if all but saved variables are lost when switching modes or turning the power off as is the case with the fx-991EX.
I have the German version (fx-991DE CW), and here the functions are NOT lost when turned off. They can also be used in a lot more places throughout, like the spreadsheet, which is a major improvement over the predecessor DE X. Pity that the user interface changed so much into menus in order to declutter the keyboard (and then cluttered the menus by having every single function you can reach via keys are also somewhere in the menus). They also did not change the two different input modes for two variable functions (like permutation or polar coordinates transformation) (which you have to know beforehand, the calc doesn't remind you), and introduced some more ambiguity (it doesn't have a solve function in the normal calc mode, as the video explains it is moved to an app, but you can still enter equation and terms for the verify function, if you select verify via the tools button. The manual you can get online doesn't explain this. There are quite a few procedures it does not explain. Yet, I guess. The thing feels like a beta release. So a newer model may be better, but you have to buy a new one, as this thing does not seem to offer any way to update the firmware.)
@@danielchan1668this is only true for China’s version the cncw one, the international version the cw will not be erasing all saved variables unless you reset the calculator😂
I became a pro with a fx115es in engineering school, and it made sense to be deeply comfortable with how it worked because exams are a sort of artificial hardware limitation. But now I do almost everything on a computer, so the occasional times I want to pull out pen and paper and calculator, I'd much rather it be intuitive because I don't really have any reason to stay at the skill level I was at with my old calculator.

Except for tiny improvements (math box: not necessary at all, with apps and other graphic calc...) i think the 991 EX is better, even if with a more messy layout and all those keys and left/ right upper keys. When you get used is fast.
The only way I've found so far is to just repeat the period/recurrence. For example input 0.166666666666666666666666 . If you put enough 6's in, the calculator will eventually recognise this as 1/6
Functionality aside, if they just kept both CW and EX models in production, everyone would be happy. Discontinuing the ex is what is pissing most people off.

Would be fine, if they allowed for some more undisplayed shortcuts, like pressing a trig while being in catalog automatically inserts its hyperbolic equivalent etc. You could still get to things the long way, but having essentially that third missing layer under CATALOG button just for "power users" who take time to learn it in the instruction would be cool.
Hi, I've been using 991EX for 6years+ now.I have to do a lot numerical Analysis calculation which requires multi statement fuction (:).Recently I bought CW as upgrade, replacing my existing EX one. I can't find the multistatement system in it? Did you?
the absence of : is causing pain. dont know why didn't they put it although there is a lot of "space" over bunch of buttons. anyway. you can use table mood for that. two multi statement for f(x) ＆g(x) if you need answers if proper fraction, that might not help for lesser than .001
Hi, is there a way that this calculator will give the general gradient function of a function, so that we can double check answers that just ask for a differentiation, not the gradient at a specific point. Many thanks
@@TheCalculatorGuide after using it for a week as an Engineer graduate I'd chose the first edition. In older version as u said in the the (ENG, SHIFT+ENG, SD, No Comp mode) are the biggest disappointment. I used these functions all the time and to use these functions i have to press few more button pains me😵😵 As for the Comp mode in order version. Comp mode let us do regular additions and subtractiona and..... others calculations easily and we didn't had to switch to equation mode manually. In the new model we cant shift+= anymore. We have to go to equation and solver manually. Only then i could shift + =. Such a pain in a ass. If u have found a way to use the Comp mode pls do tell me how. Thanks mate.
I'm not so sure about this "move". Casio has had for years now, across many models/generations, a familiar feel/layout to them. This is quite the bold move.
The old fx-83GT plus calculator is a fabulous calculator. The latest cw version looks and feels cheaply built. The display characters are smaller and harder to read. Many operations need more button presses to achieve the same thing. I do not like it. It has caused the price of the old fx83 GT plus calculators to soar on eBay! Can't believe Casio has discontinued the old calculator. Casio made such good calculators, they had completely cornered the market wiping out other companies like Sharp et cetera but they really have lost the plot with the last two iterations of this market-leading calculator.
Obviously this new model is designed for people who does not prioritize input efficiency, but ease of use without the need to read the manual. I am personally the former, but I know many people who never read the manual and weren't aware of the features other than simple calculations. I personally don't care for this model, but understand why some people will find it much easier to use than the EX.
Getting rid of the engineering and SD keys was criminal. Plus no angle key for complex math. This is not a calculator for engineers anymore. Casio messed up bad on this one. Returned mine, buying an extra 991ex to be safe.
Having a large collection of modern and vintage Casio calculators I was surprised at how bold Casio was with the design changes on this one. For better or worse they have actually broken some design patterns that have been in Casio calculators for decades. I posted my own review where I was a bit more optimistic about the changes. I think for the average student the CW will be a lot easier to use than the EX, but it does come at the expense of speed of use. I appreciate you sitting on the fence about which calculator is "best" - it really depends on the user I think.
What we want in a calculator is fast input and fast calculation power. It takes several extra steps to solve an equation than the previous models. Ultimately it affected the user experience. We don't mind to adopt a new layout but it should be more efficient, less time consuming and logical. And discontinuing the 991-ex is not a good decision by Casio
@@SanghPath What students want is to get good grades. That means being be able to understand and effectively use the features of their calculator to get accurate results and not make mistakes. Speed of input and processing is definitely a secondary thing. For most students, including the top 1%, speed is not particularly important - no one is measuring speed of answers.

Mr Calculator Guide, Can you tell me why I keep getting a wrong answer on the Casio fx-991CW? Please see OCR Paper 6 Nov 2017 (Higher, Calc) Question 5. Company produces 1.47 x 10^7 sweets/day and 3.5 x 10^5 packets/day. Calculate mean no. of sweets in each packet. I input 3.5...and I get 4.2x10^11. Crazy. But when I perform the exact same calculation (same key strokes) on the fx-85GT PLUS, I get the correct answer (42 sweets/bag). The only way I have managed to get the correct answer is to enter the values in normal notation (i.e. with lots of zeros), not standard form. Is this a bug??
Casio seems to have made a mistake in their implementation of (what used to be called) the EXP button, as it applies normal algebraic rules to x10^n, so 1/3.5x10^5 is worked out as if you'd typed "1", "/", "3", ".", "5", "x", "1", "0" "x^n", "5", which does the division (1/3.5) first and then the multiplication (Ans x 10^5). This is very misleading as it changes a fundamental aspect of how a calculation is performed and differs from previous models and other brands. What should happen is that a number in scientific notation should be treated as a single number, not a multiplication of two terms. A lot of people are going to get the wrong answer in this situation unless they apply the mantra my teacher advised many years ago "does it look reasonable?". I'm surprised at Casio for this blunder, which shows either a lack of testing or specification to test against, or a fundamental change in specification we only find out about by noticing its now odd behaviour, and they need to fix it.
@@AndrewHollom Andrew, I contacted Casio Customer Support and 'Mehak' says I should have used the button to input the numerator as 1.47x10^7, followed by inputting 3.5x10^5 in the denominator to get the correct answer. Or else bracket the two values SEPARATELY: i.e. (1.47 x 10^7) div (3.5 x 10^5). "The Casio FX-991CW, the gift that keeps on giving."
The way you are typing it in the calculator is reading this as 1.47x10^7/3.5 THEN x 10^5 which gives you 4.2x10^11 Try using the fraction button □/■ and typing your first number on the top and your second on the bottom
Sorry just realised this is what Casio have told you… should have looked at replies first. 😂 It does seem a bit of an over sight not to connect the x10^x button with the number immediately in front of it to form a standard form number.
As far as I see it, you’ll need to enter each step separately. Once you have all the steps loaded, you’ll need to go up the list of computations, select the one you want and then do the same with the next step you want. Once you have each step in the History stack, you’ll need to use the arrow keys to move up there History, select the step you want, and press EXE Tgen, it’s just moving through the history, selecting the steps and pressing EXE. Cumbersome, I agree. Casio definitely dropped the ball on this model. For the CW: Store 1 in both A & B Calculate A
They stopped the supply of 991EX in Bangladesh and replaced it with crap :") This one is very detrimental for competitive exams with narrow time limits.

The 991CW is a massive backwards step for the series and Casio. All they had to do was improve on the 991EX for example give it persistent memory and perhaps give it a better screen or CPU, but this refresh is just a joke. The design language is just awful - round keys?! This is more of a toy than a serious engineering tool. Now they have planned to do the same thing with the graphing models such as the FX-CG50. What has happened to you Casio?

Hopefully, it works as it should. EDIT: I returned it and bought the EX from ebay. Its not original but then again I don't think they sell the original anymore but it does the math that I need. No regrets. The 991EX is just better.
Guys the cw isn't that horrible, sure it takes a little more secs to calc because it has less button short-cuts, but it's processing time is considerably faster, so it cancels out the shirt-cut button time.
This calculator is a major disappointment. With three Kashio brothers already gone, and the fourth one too old, what can be expected? I request you: don't bother with this calculator.
The equation solver is now in the equation app. It has essentially been compartmentalised. You are right that I don’t believe there is a multi statement feature.
@@TheCalculatorGuide OK, but if you define a function with more variables (x and others), those vars do not shown in the numerical solver: let f(x)=A+x, jump to SOLVE and solve f(x)=10 equation for variable A if x=3.

I haven’t seen it so far no
the absence of : is causing pain. dont know why didn't they put it although there is a lot of "space" over bunch of buttons.
anyway. you can use table mood for that. two multi statement for f(x) ＆g(x)
if you need answers if proper fraction, that might not help for lesser than .001
Hi, is there a way that this calculator will give the general gradient function of a function, so that we can double check answers that just ask for a differentiation, not the gradient at a specific point. Many thanks
Then you need a programmable calculator, the one shown in the video definitely cannot do what you mentioned😂
Can we calculate remainder for a division in this calculator?
What's is best Casio 991ex or Casio 991cw?
That’s a question only you can answer. They are different enough. Casio says an step forward. I would say more of a side step.
@@TheCalculatorGuide after using it for a week as an Engineer graduate I'd chose the first edition. In older version as u said in the the (ENG, SHIFT+ENG, SD, No Comp mode) are the biggest disappointment. I used these functions all the time and to use these functions i have to press few more button pains me😵😵
As for the Comp mode in order version. Comp mode let us do regular additions and subtractiona and..... others calculations easily and we didn't had to switch to equation mode manually. In the new model we cant shift+= anymore. We have to go to equation and solver manually. Only then i could shift + =. Such a pain in a ass. If u have found a way to use the Comp mode pls do tell me how. Thanks mate.
Ex but discontinued
EX by far
I'm not so sure about this "move". Casio has had for years now, across many models/generations, a familiar feel/layout to them. This is quite the bold move.
Dude it’s terrible where’s the integrate button?? Where is t
Pepsi Man It’s in a menu now.
The old fx-83GT plus calculator is a fabulous calculator. The latest cw version looks and feels cheaply built. The display characters are smaller and harder to read. Many operations need more button presses to achieve the same thing. I do not like it. It has caused the price of the old fx83 GT plus calculators to soar on eBay! Can't believe Casio has discontinued the old calculator. Casio made such good calculators, they had completely cornered the market wiping out other companies like Sharp et cetera but they really have lost the plot with the last two iterations of this market-leading calculator.
Looks like it does the same but with more steps.
Where is the eng button. How to use it
Hidden in a menu!
Obviously this new model is designed for people who does not prioritize input efficiency, but ease of use without the need to read the manual. I am personally the former, but I know many people who never read the manual and weren't aware of the features other than simple calculations. I personally don't care for this model, but understand why some people will find it much easier to use than the EX.
Getting rid of the engineering and SD keys was criminal. Plus no angle key for complex math. This is not a calculator for engineers anymore. Casio messed up bad on this one. Returned mine, buying an extra 991ex to be safe.
Having a large collection of modern and vintage Casio calculators I was surprised at how bold Casio was with the design changes on this one. For better or worse they have actually broken some design patterns that have been in Casio calculators for decades.
I posted my own review where I was a bit more optimistic about the changes. I think for the average student the CW will be a lot easier to use than the EX, but it does come at the expense of speed of use. I appreciate you sitting on the fence about which calculator is "best" - it really depends on the user I think.
What we want in a calculator is fast input and fast calculation power. It takes several extra steps to solve an equation than the previous models. Ultimately it affected the user experience. We don't mind to adopt a new layout but it should be more efficient, less time consuming and logical.
And discontinuing the 991-ex is not a good decision by Casio
@@SanghPath What students want is to get good grades. That means being be able to understand and effectively use the features of their calculator to get accurate results and not make mistakes. Speed of input and processing is definitely a secondary thing. For most students, including the top 1%, speed is not particularly important - no one is measuring speed of answers.
@@CalculatorCulture
You are probably not from india! That's why you missed the nuances. By the way no one of my classmates considering new casio cw because of the lengthy process.
Oh you are here? Btw I am your subscriber!
@@SanghPathI agree with you and I am from India. Fortunately I have the 991EX.
Is That Upgrade Version of 991EX??? Or Equal
Casio says it is an upgrade. We will wait and see.
@@TheCalculatorGuide I think it is an experiment by Casio. They will see if users like it. If not they will get the previous model back and improve upon it.
@@Crazytesseract Let's hope so!
A parte la velocità, le funzioni son le stesse del 991 Es plus oppure questo nuovo modello ha piu' funzioni?
can you find semi colon button in this calculator

Mr Calculator Guide, Can you tell me why I keep getting a wrong answer on the Casio fx-991CW? Please see OCR Paper 6 Nov 2017 (Higher, Calc) Question 5. Company produces 1.47 x 10^7 sweets/day and 3.5 x 10^5 packets/day. Calculate mean no. of sweets in each packet. I input 3.5...and I get 4.2x10^11. Crazy. But when I perform the exact same calculation (same key strokes) on the fx-85GT PLUS, I get the correct answer (42 sweets/bag). The only way I have managed to get the correct answer is to enter the values in normal notation (i.e. with lots of zeros), not standard form. Is this a bug??
Casio seems to have made a mistake in their implementation of (what used to be called) the EXP button, as it applies normal algebraic rules to x10^n, so 1/3.5x10^5 is worked out as if you'd typed "1", "/", "3", ".", "5", "x", "1", "0" "x^n", "5", which does the division (1/3.5) first and then the multiplication (Ans x 10^5). This is very misleading as it changes a fundamental aspect of how a calculation is performed and differs from previous models and other brands. What should happen is that a number in scientific notation should be treated as a single number, not a multiplication of two terms. A lot of people are going to get the wrong answer in this situation unless they apply the mantra my teacher advised many years ago "does it look reasonable?". I'm surprised at Casio for this blunder, which shows either a lack of testing or specification to test against, or a fundamental change in specification we only find out about by noticing its now odd behaviour, and they need to fix it.
@@AndrewHollom Andrew, I contacted Casio Customer Support and 'Mehak' says I should have used the button to input the numerator as 1.47x10^7, followed by inputting 3.5x10^5 in the denominator to get the correct answer. Or else bracket the two values SEPARATELY: i.e. (1.47 x 10^7) div (3.5 x 10^5).
"The Casio FX-991CW, the gift that keeps on giving."
@@ricardo-c4l7l Either of those approaches would fix the problem, but it's a problem that shouldn't exist. Casio really are stupid.
The way you are typing it in the calculator is reading this as 1.47x10^7/3.5 THEN x 10^5 which gives you 4.2x10^11
Try using the fraction button □/■ and typing your first number on the top and your second on the bottom
Sorry just realised this is what Casio have told you… should have looked at replies first. 😂
It does seem a bit of an over sight not to connect the x10^x button with the number immediately in front of it to form a standard form number.
where to download the casion fx 991 cw emulator for windows? Thank you.
is this calculator allowed for As and A levels board exam?
I assume it will be based on what’s available.
can anyone say where can I find : in 991cw calculator
Can we use it as a replacement for 991 ex?
I think that is the intention
Don't
Having an EX myself. it’s a little more cash, but find an EX instead. The CW leaves a few essential EX features out.
I thought the 991CW emulator has not yet been released............where can we have a trial ??
It is available after you have purchased a calculator. It is available via Casio classpad
@@TheCalculatorGuide Are you saying it's now an online version instead of the normal PC version now? Thanks!
Yes that’s correct. It is a subscription model but you get access if you buy and actual calculator.

How to download or use the emulator version of 991CW calculator?
You have to buy one first. You then get a code to access it via Casio Classpad.
hi. can anyone help me with an alternative to ":" multi statement in 991CW which was presented in 991EX in Alpha ∫dx button
As far as I see it, you’ll need to enter each step separately. Once you have all the steps loaded, you’ll need to go up the list of computations, select the one you want and then do the same with the next step you want.
Once you have each step in the History stack, you’ll need to use the arrow keys to move up there History, select the step you want,
and press EXE Tgen, it’s just moving through the history, selecting the steps and pressing EXE.
Cumbersome, I agree. Casio definitely dropped the ball on this model.
For the CW:
Store 1 in both A & B
Calculate A
They stopped the supply of 991EX in Bangladesh and replaced it with crap :")
This one is very detrimental for competitive exams with narrow time limits.
Same brother with me in Pakistan I buy it today but my exam have 11 days
How to type : in this calculator. 991es can do a:b+1:c=x62+1 but this cant?
No they seem to have discontinued the multi calculation feature.
is it programmable?
No

How to do multistatements? ":" ?
They seem to have removed the multi statement feature as far as we can tell.
How i get cw emulator?
The 991CW is a massive backwards step for the series and Casio. All they had to do was improve on the 991EX for example give it persistent memory and perhaps give it a better screen or CPU, but this refresh is just a joke. The design language is just awful - round keys?! This is more of a toy than a serious engineering tool. Now they have planned to do the same thing with the graphing models such as the FX-CG50. What has happened to you Casio?
You know that sometimes most of the calculators have circular buttons so casio do this trend too *sigh*
Where is the percentage button and nCr button?
They are now available in the Catalog.

The ANS key is still there, it has just moved. It is the SD key that has been replaced.

That’s up to you really. The fx-991ex will probably be discontinued soon I imagine. The fx-991cw is new and a bit unknown. Your choice really
Where is multi statement button? , whren is clac button. Man this calculator is the example of one step forward 2 step backward
They seem to have removed the multi statement button on the newer models.
Just save yourself a huge headache and go with a TI-30X Pro MathPrint, lol
Funny, that you have "OK" at the center of the D-Pad, yet you still select menus with "EXE".
Yeah, both work.
I would avoid any CW calculator model.
Please tell me as soon as possible
Horrible calculator. I bought 991ex instead
Yeah I’m about to return this calculator and buy the 991EX as well. Unfortunately, I couldn’t find the EX in any stores, and eBay looks like the only place where you can purchase it. Hopefully, it works as it should.
EDIT: I returned it and bought the EX from ebay. Its not original but then again I don't think they sell the original anymore but it does the math that I need. No regrets. The 991EX is just better.
Guys the cw isn't that horrible, sure it takes a little more secs to calc because it has less button short-cuts, but it's processing time is considerably faster, so it cancels out the shirt-cut button time.
This calculator is a major disappointment. With three Kashio brothers already gone, and the fourth one too old, what can be expected? I request you: don't bother with this calculator.
It will probably become the standard model though, so I probably will to keep up to date.
@@TheCalculatorGuideThat is entirely up to you! What you say makes sense, however it has major design flaws in my opinion.
Who thought the Format button was a good idea?
I like the name change, but it would have been so easy to make it a toggle and the menu as a shift feature
@@TheCalculatorGuide yeah exactly. Other than that, I actaully like this one more than the 991ex model. It'd just need time to get used to I guess.
@@silverphoenix_1756 Agreed. The more I've worked with it the more I quite like it. Just getting used to different practices really.
There is NO CALC, NO SOLVE for ANY variable, NO multistatement (:) - this is an useless calculator, greatest drawback in CASIO's history.
The equation solver is now in the equation app. It has essentially been compartmentalised. You are right that I don’t believe there is a multi statement feature.
@@TheCalculatorGuide OK, but if you define a function with more variables (x and others), those vars do not shown in the numerical solver:
let f(x)=A+x, jump to SOLVE and solve f(x)=10 equation for variable A if x=3. There is no SOLVE for A only for x. Or mybe I'm miss something?!?
And where is CALC?
Unfortunately, they discontinued the old model, so now we are stuck with mimimalist garbage.
very ugly calculator
Your just still stuck on 991 ex right?
