fx-115ES PLUS 2nd edition - A Brief Overview

Picked up a new fx-115ES PLUS 2nd edition (US) -- I believe it is marketed as the fx-991ES in other countries.
The video provides a brief overview of the calculator as compared with the 1st edition. It seems to have nearly identical electronics in a new, prettier shell.

[@ricklynch]

I have all three of these calculators. The 2nd Edition Fx-991es Plus C (Canadian version) is all black like the Fx-991ex. Matches nicer. Also found doing an Integral 0,6 e^x^3 is about a second faster than the 2nd Edition. The ex smokes both of them! Still love my HP 48sx though! Use it, the 48gx & 50g. Don't have the Prime..... Yet.

Thanks. I came here for recommendations and was suggested by a couple of merit listers 👍

[@scottcollins7513]

Glad you found it helpful and appreciate you leaving a comment. I really like the fx-115ES -- I actually prefer it over the fx-991EX. It's much slower, but I find it more intuitive and like the bigger font. There's a deeper-dive video available here if you are interested --> kzbin.info/www/bejne/bHvClpuGichjntk

Meh...i am not a keen fan of cosmetic changes in products

[@MrMarcec85]

They made the EX and they lave out functions.... I am confused and buffled. They made a German version DEX with 696 functions. In Italy we din t even have the 115es plus/ 991 es plus Canadian. We miss lcm and gcd, cuncurring numbers and disequations solver, plus other stuff. Honestly it s a very bad commercial strategy. I will look at other brands.

[@scottcollins7513]

Agree. It is very strange how much variation there is. The German 991DEX sounds like a winner.

[@AprendizDeLoQueToca]

@@scottcollins7513 Iberia also

[@atFanta]

They all do the same right? I don’t mind if one is slower but I need one for physics class. Are they all the same or do they have different ways of doing the same calculation?

[@scottcollins7513]

The three calculators in the video are very similar in terms of how they function. There are slight differences, but they are subtle. Any of the 3 would be good for physics class. The speed difference is insignificant for any typical calculation you will do in physics. This video goes into more detail if you are curious: kzbin.info/www/bejne/bHvClpuGichjntk

@@scottcollins7513 thanks, i first tried the fx 115 and the blue tinted screen with the low quality made me return it. Unfortunately the 991 ex is not being made anymore and I had to get the 991 ES, it’s basically an upgrade right even though it looks cheaper?

[@scottcollins7513]

@@atFanta The 991CW is the replacement for the 991EX (in the US) -- www.casio.com/us/scientific-calculators/product.FX-991CW/ 115ES PLUS 2nd edition is replacement for 115ES PLUS (in the US). The 991ES is extremely similar to the 115ES, but there might be slight differences in functions. Bottom line is that you have a solid calculator in the 991ES that should serve you very well. I have not personally tried the 991CW.

I find out that 991 model does not have Row reduce echelon form like the 115 model. TI 36xpro and casio 115 model both have that feature.

[@scottcollins7513]

It is a mystery how they decide what to include/exclude on these models. Thanks for pointing this out to anyone taking a deep look into what these different tools offer.

I hope u can answer me.I am from Bangladesh. Here we use 991 es plus or 991 cw.My cousin bought 115 es plus for me from US.Are u sure that 991 es plus and 115 es plus are the same calculator?The website shows that 991 es + has 403 functions whereas 115 es + has 257 function.I am not sure.

[@scottcollins7513]

I am not sure about anything in the crazy world of calculators. There are too many variations of calculators made for different markets. If the website shows 403 function for one calculator and 257 for another, I think they are significantly different. Sorry I am not more help. Glad you are doing your research.

@@scottcollins7513 I am an engineering aspirant.So Should I look for a calculator with more functions or just keep it?It would be very helpful.Thank u so much

[@scottcollins7513]

Just make sure that your 115ES Plus has the solver function (shifted function of CALC key), handles matrices/vectors, and has numeric integration and derivative. It should definitely have those if it is a USA fx-115ES Plus, but worth making sure. I think if it has those you will be fine with it.

@@nomshif4698 I cannot speak to how long they last, but we’ve been using ours at school for 4 years and they are fine. The 991EX Classwiz has higher resolution display, faster processor, and better build quality than the 115ES.

Made in which country?

[@scottcollins7513]

I'm guessing it might vary based on the country you live in, but mine was purchased in the USA and is made in Thailand -- always refreshing to see something other than "made in China".

[@zorosan-f7n]

can i ask you wt should i buy and who is better on exams ?

[@scottcollins7513]

If you have good/young eyes, the fx-991EX Classwiz would give you the most value and has a much faster processor. I think the fx-115ES PLUS 2nd edition is easier to read and slightly easier to use. Either of them will serve you well.

[@13rooke57]

Question I hope you can answer! I recently had to change one of the modes on my calculator and every since I've noticed a few different things that weren't like this before. When I go in to add a fraction, before it would let me put one number over another like a normal fraction would look like, but now it just gives me this weird backwards L shape. I've also noticed that when I go to add an exponent, it gives me the same symbol but with an arrow and parentheses, whereas it used to give me a dark box to insert my number in the exponent spot. These are small details that are really annoying to me because now I get less accurate answers and this is the calculator I use for my Algebra 2 class. I have no idea how to reverse it, so I'm hoping you do.

[@scottcollins7513]

Two thoughts: (1) You accidentally went into complex mode. Click "MENU" button and type "1". This will put you in normal mode. (2) You changed the settings by accident. You want MathI/MathO setting -- explained in this video: kzbin.info/www/bejne/m5ezqWyjrZd-npY

how do I get my answers to be a decimal instead of a fraction when I divide on the middle calculator?

[@scottcollins7513]

You will want to press the "SETUP" (shift-"MODE") key (to the left of "ON"). Press "1" for MthIO. Then press "2" for "LineO". When you type 22/7 you will get 3.1412857143 rather than the fraction 22/7. To go back, press "1" for MthIO, then press "1" for "MathO".
