Very helpful. I've had this calculator for years and have not been able to figure this out. Thank you
Thank you for helping me learn about the matrix functions of this calculator. It’s much more powerful of a device than I thought!
this is the best calculater ever. I use it more than my TI-84
``inddeed it is. Very user fiendly and powerful.
I really love your video! It saved me so much time for my classes, keep up the good work!

you are welcome.
My calculator is an fx-570LA Plus but it don´t suppor RREF function 😭
I learned a few tricks on my calculator. Thank you.
you are welcome.
how about saving the result. Lets say, I inversed the matrix A. Cant I save this result as matrix B?
Whatever you have, you can save it and I should have shown it or you may have skipy
@@equaser I watched the full video again to make sure. So, no you didn't show it.
this was incredibly helpful, thanks a lot
I am glad you found it helpful. Here all features of this calculator explained with better contents th-cam.com/video/-ldSlx5VMo0/w-d-xo.html
Nice video I will subscribe 👍
Nice 👍
thank you,without your experience I would be waste
you are welcome.
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?
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.
Thank you so much!!

Is there a way to do REF and RREF on fx-991ES PLUS? I can't seem to find those options in the menu.
sorry not possible. Only you gotta do it manually.
Equaser.com Ok Thanks!
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?
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.
@@equaser can fx 991ex plus do ref or rref?
tks ^^
wlm.😊
Brother please calculate echelon from using 991ES plus calculator
if it doesn't have the option, you can't do it.
does this work on casio fx300es plus?
If matrix option is available, then yes
Can we do it if it’s a 4x4 matrix?
I have demonstrated it. I mentioned what mastic size it can do. Please watch.
Can u tell cheapest calculator which supports 4x4 matrix and also rref
Fx-991ex Casio. 4x4 means the top clay which is very cheap.
Thanks Sir
you are welcome.
how to find REF in casio fx-991Ex??
If it was available, I would have shown you.
Ref meanings
I mentioned it in video. I didn’t just select that option. REF = row echelon form
@@equaser whattt

Yes. here th-cam.com/video/lzVylUyqFQo/w-d-xo.html
