Pros for the 991cw: 60min time out, spreadsheet data is not lost when switching apps, stat data is not lost even after power cycle, f(x) and g(x) can be used in other modes including spreadsheet, it is a little faster to process long calculations. Cons for 991cw: It is dumbed down to appeal to first time calculator users, so it it slower to use in general, lost the multi-statement colon ":", fraction decimal view switching is painfully slow. If you can live with those downsides, then the 991cw is an upgrade to the 991ex. If you want the best calculator, just get a TI-30X Pro MathPrint. ;)
I absolutely hated the TI30X Pro. The only advantage is the copy paste feature and that it keeps storage. Buttons feel horrible squishy, for e.g. variable d you have to press one button like a thousand times, whereas on the fx you can just put them behind each other without multiplication sign and you also cant missclick. Also readability is much better on the fx991 X. Square Root under 2nd is also painful to use everyday. Also you cant to things like cos(cos( cuz it switches to arccos.
You can change decimal to fraction or vice versa very easily with CW- Just go Calculate> Press settings button> calc settings> Input/Output. ChaNge MathI/Math0 to MathI/Decimal0 for decimal. All your answers will have a decimal format now. Switch back to MathI/Math0 for Fraction.
2:39 quite wrong, the fx-991EX has a place where you can see all the values. And, if you’re wondering 💭 how to change the value easier; you have to… 1. Turn *on* your calculator (why not?) 2. Pick a *number* 3. Press the equal button **=** 4. Press the *shift* 5. Press the store button **sto** 6. Press the equal button 7. You’re done! Now press *ac* That’s all, nice and simple :)
I bought a CW right after they came out, and I was disappointed. The CW feels cheap, especially the snap-on lid. I much prefer the keys on the EX. I am surprised that you did not mention the biggest change - many of functions on the EX, that are key presses with Shift or Alpha, have been moved to menu items on the CW. The result is that it takes longer to find the function you want and usually there are a couple of more key presses to get what you want. For me that was the deal breaker. Most of the rest I agree with you, especially when you said it seems like Casio went a step backwards. I gave my CW to a colleague. As for the carbon fiber look, I have the Casio fx-CG50 and the Casio Classpad 400 CAS, and they have it too, so it's like having a set. Another feature of the carbon fiber look is that it does not show every little finger print like the shiny colored plastic does. I think I'll just hang on to my two EXs for now.
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.
2:40 you are absolutely wrong about that part. The 991 ex does show you all of your variables in a single screen once you press shift and store button. And honestly speaking, the variable recalling experience is much convenient on the Ex than it is on the CW
Hi @The Calculator Corner Love your vids just to correct things up 2:19 in calculate (or complex), if you press shift + sto, you will see a menu of stored variables just like the cw and to store a value you could either, 1) enter a value to the calculator screen and then press equals, then press sto, then press the letter you want to store it to (pressing alpha is optional, you just have to press the button which has the letter) 2) if its an answer of a calculation u just got in the calculator, press equals, then press sto, then press the letter you want to store it to (pressing alpha is optional, you just have to press the button which has the letter) or as you have solved the previous calculation already, you could just press ANS, then press equals, then press sto, then select the letter
4:20 I don't get your biased obsession with the CW. The EX will solve you an equation and do other calculations later on the same screen. On the CW you need to access a special mode to solve a equation and come back to Calculate to do further calculatioms. The EX clearly won in terms of convenience. Nobody likes pressing more buttons to solve an equation than they used to.
This is a good comparison. Video content is good! I see that the calculators aren't fully visible in the frame, which is very apparent while demonstrating the sliding mechanism. My only suggestion would be to improve the framing :) (wishing you on your future ventures)
I'm a new engineering freshman and this is my first scientific upgrade from the good old TI-30XIIS, so I couldn't care less about the minor controls and layout changes with this model that a lot of people on the internet have been whining about lol. I much prefer the clean black design over the fake carbon fiber and chrome EX anyhow.
If I was a freshman engineering student again, I would get the TI-30X Pro MathPrint. Way better than any Casio IMO. (coming from someone who finished an engineering degree, passed the FE, passed the PE (CBT) , and is a working professional).
@@wb.c I considered it, but after getting this (and also a CG50 for cheap), I realized how much I hate the way the TIs work. For example, the order of operations, or the multi-layer menus of the graphing ones.
@@ironmatic1 To each their own I guess, but I honestly would stay away from advanced calculators for school. You can’t use them on the FE or PE, and you won’t use them for work. Stick with the calculator that is allowed on the exams. I started with Casio fx-115 and then used a TI Voyage 200 for most of my studies, had to learn how to use a new calculator for the FE.
Speaking of setting variable to some value, on EX you can type the value, press STO (short for store) and press corresponding variable key. In my opinion, the only real advantage of CW is ability to use f(x) and g(x) in other modes.
Hi there! Engineering student here. I use my 991 ex a lot to do complex equations and save time. I haven't got any chance to use a cw myself but watching videos of people using it I can say my ex can do pretty much everything the cw does. Casio have added new features to the CW but made it less user friendly. The difference between these calculator is pretty much negligible since both of them have everything I would ever need to use. In summary I would like to say that in the ex you spend more time getting your results and less time entering your problems
@@saujanyapoudel8910 thanks but I already bought the CW My sister has the EX and a friend of mine has the CW and I tried them out and I found the CW easier to use
When you have to store a number into variable on EX by solving an equation for that variable, it just means that you shoud RTFM before trying to do some comparisons. The manual is thin and well written. That part of the video relly looks like a very bad case of teleshoping. After about 2:30 I lost inerest.... Sorry, just my opinion.
You can also use FUNCTION f(x) and g(x) on FX-991EX, it is in TABLE mode. Just like with RECALL (to shall all variables) you missed a feature that exists in older model (where it is better implemented than in never model). Unfortunately ergonomics and quickness of usage is downgrade in new model. Screen font and speed is upgrade. I own older model (FX-991EX) and use it a lot. Dice roll is one of few "new" features, but you can easily simulate it easily with random number generator. Summary: New FX-991CW is dumbed down version of old FX-991EX with features hidden behind scrolling lists, with no option to use numbers for shortcuts. FX991CW may be better for unexperienced users, but will lag in speed behind experienced users of older model (less keypresses to get the same result are needed in older model).
Yes, but the CW also allows you to define f(x) and g(x) use either of them to calculate specific values based on x, or even to solve equations involving composite functions, e.g. gf(x)=1, using the 'Solver' facility in the equation solving mode. The styling of the EX is much better, but the CW is more purposeful, and the keys feel better (firmer and more positive).
CW os such a disappointment. I had to shift back to my 5 yrs old EX back right after using for a week. Getting the value is much faster but everything else is such a hassle. The quadratic equation,The ENG button and all other small stuffs. I regret buying the cw
2:15 Read the manual. You obviously don't know how to use EX variables. Instead, you use a convoluted method of storing and recalling variables. This makes you look bad and disqualifies you as a reliable reviewer. On the EX, [Shift][STO] (RECALL) to see all the variables on a single screen. To edit, simply type the value, followed by [STO] and the letter. The CW has added additional steps, more explicit but less convenient, through several menu items to achieve the same thing. There is no new functionality here. You are just mistaken.
Been looking everywhere for a legit 991EX, there are so many fakes out there. I really don't like the new calculator, they should never have moved away from the original layout.
