Casio fx-115ES PLUS vs. Casio fx-991EX CLASSWIZ

Comparing the Casio fx-115ES PLUS to the Casio fx-991EX CLASSWIZ

[@RonaldModesitt]

Nice presentation and exactly what I was looking for.

[@OnePunchMath]

Thank you very much!

[@batakadventurer4875]

How much is it???

[@liajuns5829]

Thank you, I was having this exact doubt when choosing which one to buy, mostly because of the similar functions and price. Spot on video!

[@OnePunchMath]

Thank you very much! Glad it helped.

[@luisramos3427]

Thanks for the advice👍

[@OnePunchMath]

You're welcome!

[@Crazytesseract]

Do you get the fx-991DE X in USA? It is the German version of the ClassWiz 991EX. It has those functions like Product, remainder division, Int, Intg etc. which the 115ES plus has.

[@OnePunchMath]

Not that I know of, but it can be ordered online through amazon.

[@ser7ser7i]

Thank you, really helpfull.

[@OnePunchMath]

Glad it helped.

[@christinebalicao5309]

U seful review. checking what calculator to buy for my daughter over these 2 options. Thank you.

[@OnePunchMath]

I would go with the Classwiz. 😊

[@czluver4338]

One advantage the 115 has over the 991 is LCM and GAS which can be a huge time saver.

[@OnePunchMath]

Yes, it appears that the CLASSWIZ does not have the LCM or GCF functions built in. I just scrolled through the entire user manual to verify this.

[@Crazytesseract]

@@OnePunchMath fx-991DE X the German version has almost the same functions as the 115ES PLUS.

[@Centar1964]

See the CASIO FX-JP900-N

[@rubennishwaraankaruppiah3707]

what is LCM and GAS?

[@orangecaprinun]

Have u considered doing an Fx 115 es plus second edition review and comparison to the ex classwiz ?

[@OnePunchMath]

No, but I will now. Thanks for the comment!

[@orangecaprinun]

@@OnePunchMath thanks !

[@MrMarcec85]

Is it true you dont have LCM and GCD on the new FX991ex? And also the peeiodic decimal conversion. Also. We in Italy don t have the 115es... what is it? Our line up (classwiz only) is 82 350 (which have the same functions on the site) and the 991. I ve seen the fx991ES 2nd ed and other models.. but it seems confusing.

[@OnePunchMath]

Yes, however there is a FACT function which will give the Prime Factorization of a number. You can use that to help find the LCM and GCD of a set of numbers. I personally would go with the 991 over any other Casio model based on the cost/functionality ratio.

[@Centar1964]

The CASIO FX-JP900-N does and a periodic table too!

[@rachellua5481]

Is it possible to do polynomial simultaneous equations on the classwiz?

[@OnePunchMath]

No, just linear simultaneous equations. DESMOS is a good, free alternative if you just need help with checking your manual solutions. It only gives decimal approximations for the points of intersection, but it's super easy to use.

[@rachellua5481]

@@OnePunchMath fair enough, I don't think examiners would like the idea of me not showing my working out during polynomial simultaneous equations. Indeed desmos is good

[@opablo_gm]

have you noticed that you would be loosing at least one nice feature in that upgrade ? the repeating decimals input+output is lost

[@jadensharper6193]

For some reason, I’m not able to sort the data within the list. I’m in a statistics class & the list must be sorted to solve the problem.

[@OnePunchMath]

As far as I can tell there is no way to sort a list in the Casio fx115es plus or the Casio fx991ex Classwiz.

[@erynmarpaung9689]

There are some stats app in android play store (free). Lite but quite powerful

[@andreasxfjd4141]

Does the fx-991 ex save the calculation history?

[@OnePunchMath]

Yes, you an scroll up and see previous entries.

[@tiskolin]

There seem to be missing functions on the CLASSWIZ; the matrix, vector, etc buttons on the keypad are missing. Also, the PreAns is missing as well.

[@arielkuz]

Those functions can be found by pressing the OPTN button, which can choose modes (matrices, vector, etc)

[@OnePunchMath]

As far as I can tell, the Ans button serves the same function as the PreAns function, so that doesn't seem to be a big issue. On the CLASSWIZ, the OPTN button seems to take the place of the MATRIX, VECTOR, ect. functions on the 115ES PLUS. I was very disappointed to find that the CLASSWIZ does not have the Ref and Rref functions for matrices that the 115ES PLUS has. Thanks for sharing!

[@bilAlAlAm_25]

What Is The Use Of : button in a calculator..either in fx991ex or in any other?

[@OnePunchMath]

It is used in Spreadsheet Mode in the same situations that you would use a colon (:) in MS Excel.

[@silentgamer1605]

My best calculator is fx-991ES

[@user-qj3pd2cv6n]

Me too

[@kkhang8617]

If you are in the hard math exam, you should use fx-115 which is less function but faster.

[@OnePunchMath]

I disagree, but to each his own. 😊

[@silentgamer1605]

Sir please 🙏😁 reply me who is better

[@OnePunchMath]

The fx991EX, IMO.

Is it possible to show function graphs in FX 991 ES PLUS?

[@OnePunchMath]

It's not a graphing calculator.

Lol nope hahaha but it will give the XY min and max🥲
