Can we get the inverse of a matrix using fx-991es?
By the way, I have been googling to buy a scientific calculator. The more I google, the more I can't decide. So, can anybody please advise me the right model? I'm an electrical and electronics engineering student, and I want to use the calculator which can help me throughout the undergraduate program. Until now, I have found these alternatives; fx-991ES , fx-5500LA , fx-5800P. Well, the last two options are a little expensive compared to fx-991ES. Also, I am kinda interested in fx-9860G. Do I, as an electrical and electronics engineering student, need the graphing calculator? I would be very much appreciated if I can get some quick replies.

If you are planning on taking an undergraduate or any university course, then I would advise upon a powerful graphing calculator. Despite the fact that the fx-991ES can only do simple matrix operations, you really need a graphing calculator.
For what you are asking, take the fx-9860G. If you will put up with a used one, then try ebay.

Hope that this helps,

Step 1: input the matrix
[Mode] Matrix
![]()
(MATRIX)
(Dim) And then select the matrix name you want to use (
(MatA),
(MatB) or
(MatC))
Next chose the matrix size.
And then input the matrix element.
After inputted 2 matrix you want to use, to turn back to the input screen, and then, for example, if you want to mutiply MatA and MatB, press![]()
(Matrix)
(MatA)
![]()
(Matrix)
(MatB)[=]
