- 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.
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.
good review, and good comparison between the two editions.
Omg the features on this calculator for just $15 is amazing
perfect. Thanks!
Nice video, thanks for sharing with us, well done :)
Thank you, Mr Bianchi, for the kind words and for taking the time to leave a comment.
thanks for the video ,
You are welcome -- thanks for leaving a comment, JCC.
Great video scott
Really appreciate the encouragement.
@@scottcollins7513 as a teacher of statistics, I recommend the fx-115ES Plus. Thank you for reviewing this new 'edition', which I just discovered at Office Depot's website, searching for prices to communicate to students.
Thanks. I came here for recommendations and was suggested by a couple of merit listers 👍
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 --> czcams.com/video/6J_ehPTc0hw/video.html
@@scottcollins7513 thanks so much🙏
Scott, nice find! I think the fx-115ES plus is an amazing bargain. I will have to start searching for the second edition.
Thanks, Detron. I stumbled onto the fact that there was a new 2nd edition and was able to find it at Target (US) the other day.
@@scottcollins7513 I checked Amazon and Walmart.com. I will keep my eyes open for one.
A calculator hunter? Nice
@@detronbrian btw is the Casio fx-991 es plus second edition rare we than the best one?
@@TheOnlyMusty I do not have a 2nd edition yet. it appears the only change is the outer shell design and shape.
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.
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: czcams.com/video/efPx9mx2Kh4/video.html
@@scottcollins7513 The link to the video helped, it's fixed now! Thank you so much and have a good day!!
@@13rooke57 Glad that did the trick -- thanks for letting me know. You have a great calculator for Alg II, PreCalc, and Calculus.
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.
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.
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
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.
I have the Casio 82ms, fx-570EX classwiz, and TI Nspire CX II CAS🤣
The Nspire is my favourite😅
can i ask you wt should i buy and who is better on exams ?
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.
@@scottcollins7513 omg thx for your review i will buy fx-115 es i think its better
I’m 25 I got the blue one in 9th grade (13) and it just died on me lol
ibox107 That’s some respectable battery life.
So, which one should i buy?
I think for most people, the fx-991EX would be best.
@@scottcollins7513kindly, can you tell the reason?
And why they don't work after two or three years?
@@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.
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.
Agree. It is very strange how much variation there is. The German 991DEX sounds like a winner.
@@scottcollins7513 Iberia also
how do I get my answers to be a decimal instead of a fraction when I divide on the middle calculator?
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".
Made in which country?
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".
Meh...i am not a keen fan of cosmetic changes in products
