What is the : next to calc button

[@equaser]

watch to see how it is used. This is exactly why I made this video so nothing is left out.

[@SJY11]

I haven't even finished the whole video yet, but already I am blown away by how well this video was made. It's clear that you spent a long time creating this video and you paid attention to each and every little detail. There are timestamps included, and you even have the PowerPoint presentation on the right! I was trying to find a video that explained each and every feature of this calculator in detail, and this was the only video I could find that went into such depth! Kudos to you, Ahmad! 👏

[@equaser]

I am glad you found it useful and appreciate your comment. stay safe and thank you .

[@vascobishop3359]

It was nice to see the presenter at the end of the lesson. We had a guided session without any interruption. 10 out of 10 here.

[@bruceisaak3734]

I was looking to buy a basic scientific calculator for project calculations. This calculator was one of the least expensive options at Walmart. I had some trouble figuring out how to enter calculations so I looked for a tutorial to learn how to operate the functions on this calculator. I managed to follow this video and replicate all the examples up to complex calculations. I watched the rest of the video but realized I was not familiar with those math functions. It now looks like I need to dig in and learn some new math to understand the rest of the math behind the remaining functions. Thanks for the fantastic presentation. I have subscribed and saved this video under a new folder called HOMEWORK.

[@ushapadhi5527]

I lost my manual and I was constantly slowed down on the SAT practice test because the answers always showed up in fraction and then I had to go back and do the calculation again ,this video was a life saver tq

[@equaser]

Glad it helped.

[@nicolebyrum9665]

Thank you so much for this video! I got my calculator yesterday and this helped me to figure out why all of my equations kept saying error. This is an extremely well put together and insanely informative video that I would recommend to anyone trying to learn!

BRILLIANT!! SO clear, concise and super well done!! By far the best I have seen!! Thank you!!

Very Professional effort. Not seen as patient and precise walk-through. Casio unfortunately has a very confusing and poor system of manual and support. This gentleman has made a video on fx991EX Classwiz, which he calls "Manual" and is actually far better than the casio's own manual. 👍🏆🏅🥇

[@aashroan]

Does the C in the calculator in this video stand for classwiz ?

[@abiodunadeyemi4040]

A warning about using the (-) button..... it acts like you've entered -1 times whatever follows so that if you enter this: (-) 1 and then hit the x^2 button, you get -1 times 1 squared = -1 and not (-1)^2 = 1. You should either use parentheses or hit Ans after the combination (-) 1 to have -1 as the working variable.

[@iamtheiceman]

Very helpful video. Only wish you zoomed (out) a bit more so we could see the buttons you are pressing a bit better. It is too bad the actual manufacturer does not take accountability to do a video like this to explain their complicated product. Thanks again !

[@equaser]

Zooming out would make the text look very small. You must have skipped where at the binging I said I will show they by brining the calculator up on the screen for the first time. So you gotta watch from the beginning to learn and have no complaints.

[@frin.-]

Thank you so much for this video! I was completely unfamiliar with this model and now I'm managing well thanks to you.

[@shad6519]

When you press one, you should show us. How do I use as addition numbers. This is for beginners.

Of course it has been shown. I showed once and then I said I mentioned the key. You see the equation or symbol on the screen.

You are most welcome my sister.

[@bonbonpony]

So this calculator only allows entering formulas and then fully evaluating them? It doesn't allow doing calculations on the fly? On some calculators, you can press, let's say, [2] [9] [-] [3] [=] to get 26, and then if you press [=] again, it repeats the last operation (subtracts another 3) with every [=] press. Can this trick be done on this calculator too?

Is there a mode setting where the SD button will allow me to switch between a fraction result, the decimal, AND the scientific format.? My old Sharp used to allow this.Thanks

[@equaser]

What does the SD but do now then? It does exactly what you are looking for. Only if not possible to make fraction it won’t work. Else it works

[@MyTutorGuy]

@@equaser For example, in default mode (math io 1 / norm 1), 890 /56 is either 445/28, 15.89285714 with a bar over the last 6 digits , or just 15.89285714 using SD button. In this mode , scientific notation does not appear (I.e 1.589285714 EE 01) Norm 2 gives the same result. If I switch to SCI mode 0 , the SD button offers scientific mode for 890/56, but other calculations appear to disable the SD button in this mode. Eg Combinations 20C5 gives only 1.5504 EE4 and the SD button does not flip it to 15504. Same with say 56tan(20)= 1.2528 EE 2. Again SD button has no effect if I want to display as 125.28.

[@equaser]

Just reset the calculator and it will work the way you want it.

[@MyTutorGuy]

@@equaser That does not produce scientific notation. In SCI mode, the calculator produces what I want gor simple calculations, but not for the output of functions, which is strange.
