[@bulutosman]

how about saving the result. Lets say, I inversed the matrix A. Cant I save this result as matrix B?

[@equaser]

Whatever you have, you can save it and I should have shown it or you may have skipy

[@bulutosman]

@@equaser I watched the full video again to make sure. So, no you didn't show it.

[@brenmclean]

Using the calculator, I find REF is correct, but RREF is not. For example, matrix B is inconsistent and does not reduce to identity matrix. Thoughts?

[@equaser]

In the manual I believe I have read somewhere it says that you will not always get (correct) answer. So it could be an exception. Try different matrix and most should get correct answer.

[@ArnavSinghVEVO]

Is there a way to do REF and RREF on fx-991ES PLUS? I can't seem to find those options in the menu.

[@equaser]

sorry not possible. Only you gotta do it manually.

[@ArnavSinghVEVO]

Equaser.com Ok Thanks!

[@ArnavSinghVEVO]

Equaser.com Why is there such a different? Even though 991 is a newer model. I have been using it for a very long time. Which model do you suggest?

[@equaser]

FX-991ES Plus C and FX 115 ES Plus can do it. if you are not looking for RREF/REF in matrix, then get FX-991EX which is much better.

[@omnibrain8]

@@equaser can fx 991ex plus do ref or rref?

[@wilbardschillo8559]

CAN fx-991ES PLUS DO RREF ??

[@ahmedtheking123]

sadly no

[@rajitbansalrocks]

Is Fx991es plus same as fx115es ? secondlu can it be done on fx991ex ?

[@CodehanCodes]

no sir 115 has more features

[@elmerares1540]

i consider casio fx-115ES (plus) the most advance amomg the casio scientific calculators

[@jbbudish]

wow I would have done a lot better in my engineering courses if I had known how to use my dang calculator...

[@equaser]

Yes. Actually I started making video by noticing that many students in my class didn't know features of calculator.

[@sumankhanal4607]

Brother please calculate echelon from using 991ES plus calculator

[@equaser]

if it doesn't have the option, you can't do it.

[@peeyansh]

does this work on casio fx300es plus?

[@equaser]

If matrix option is available, then yes

[@souradeepdey1338]

Can u tell cheapest calculator which supports 4x4 matrix and also rref

[@equaser]

Fx-991ex Casio. 4x4 means the top clay which is very cheap.

[@user-vj4fx2oe7f]

Can we do it if it’s a 4x4 matrix?

[@equaser]

I have demonstrated it. I mentioned what mastic size it can do. Please watch.

[@ScamAlert1001]

how to find REF in casio fx-991Ex??

[@equaser]

If it was available, I would have shown you.

[@abidaiftikhar1420]

Ref meanings

[@equaser]

I mentioned it in video. I didn’t just select that option. REF = row echelon form
