To anyone trying to make a choice: 1) In practice, the speed of these calculations does NOT matter. 2) The ONLY thing the CW does better is the SOLVE app, which is now in a menu. And it only does it better because it is more practically stable (the EX has a tendency to lose entries when you press the wrong button, while the CW is more likely to keep whatever you have painfully typed in). 3) The CW changes some simple fundamental things or makes them more clunky by putting them in menus. One of the most problematic for me (a calculator user for over 40 years; if you only learned this one, things may vary) is the changed behavior of the "x10^n" button, which replaces the "E" button. In the past (that is, ALL calculators made in the past who had this functionality) this button was used to enter an exponent in scientific notation which was part of the number you entered. Now it's actually a product, with the exponent of the ten NOT part of the number. (Entering "1/3x10 3" gave in the past 1/3000, entering "1/3x10³" now gives 1000/3. The labeling printed on the button remains almost identical.) This makes many calculations in physics more clunky and requires more attention to details like extra brackets.
The font of the EX looks better, the speed of the CW is greater... tough to decide which to get! Or I'll be like you and buy both. Thanks for the video.
With this side by side comparison, I do like the clarity of the fx-991CW font and clearly it is quicker. Thank you.

Nah, the clean look is way more elegant. The EX looks impressive at first, but the fake carbon fiber and chrome just ends up being tacky.
Where can I buy the EX now that its discontinued?
Great video. Thank you!
How to calculate integration in this Casio please enter the tool in reply
Go to catlog and then function analysis there you can see integartion
My fx570 took 1 minute to solve that integral
You will regret buying the new models due to lack of many important buttoms. It sucks
In the 991CW, it is not the lack of the functions themselves, but the fact that they are time consuming to find (scrolling through menus).
