Casio FX-85 calculator comparisons between versions

In this video I compare the Casio fx-85 ES, Casio fx-85 GT PLUS, Casio fx-85 GT X, and the Casio fx-85 GT CW calculators to see some of the changes Casio made between each iteration.
To Casio: please don't sue me. I only have £9÷3(1+2)×10¹÷1×10¹ in my bank account

That whole headache with the ÷ operator is the reason I only use fractions with a number over another. I find it a lot more intuitive. Not that I can't use ÷, but when I do I always use bracketing everywhere to show exactly what I want it to do, which is a pain, but a lot more consistent between calculators. A fraction is a lot faster to type.

I wish a calculator manufacturer would put implicit multiplication as a selectable option. It would solve the problem of different education systems handling it in different ways. Personally, I quite like the Casios, but the CW's design changes were a bit misguided if you ask me. They seem to be doubling down on that direction though. IMO, the TI-30X Pro Mathprint is better, but they're not common here in Casio land (the UK).

Agree all CW calculators are rubbish. I tell all students to avoid ANY Casio CW calculator . The OS is dreadful , particularly with scientific notation. The case is awful, cheap and plasticky. One point though : To convert output 1/3 to decimal on the CW press "shift>EXE". 0.33333. All calculators are supposed to follow BODMAS = ()^2/x+- But 3(3) is not usually considered a legitimate way of entering 3x3. If the x sign is used I think they all give the same answer.

The ‘S’ on the ‘S-D’ button stands for surd.

The new design is a bad. I have the both versions of the FX-991de X and the CW. The CW is a overcomplicated menu-monster. I could not believe they moved the % key to a submenu. I like the round buttons but why do they have to make a very good device like the X and turn it into a thing that should fly out window and into the trash after 5 minutes of use? Oh yes and that i cant choose menus with numbers... what where they thinking? I know why i love the DM41/DM32/DM42 so much!

DM42 is the greatest of all time (in my opinion) 😂 in other news, my HP15c CE just arrived recently. I love that calculator

They may be ok for physics, but they are not enough for engineering. We need fx-991 or 570 models. And, avoid the CW models at all costs. Not all the Casio calculators are bad, if you know how to use them properly.
