Hello,
I will assume you are familiar with the basic concepts of matrix algebra.

Turn calculator [ON]
Press [MODE][6:MATRIX]. Select the matrix you want: MatA, MatB, Matc
Let us assume you select 1: MatA.
MatA (mxn) sceen: there you specify the dimensions of the matrix, the number of rows, and the number of columns. Press 5 for a 2x2 matrix.
The matrix entry screen shows, a rectangle is highlighted. Enter there the a_11 coefficient, exemple 1.
1 [ENTER]. Highlight moves to a_12 ;
1 [ENTER] highlight moves to a_21
1 [ENTER] highlight moves to a_22
2 [ENTER] Highlight stays on a_22.
Matrix is defined. The values I used are arbitrary. Enter your own.

Suppose you want to calculate the determinant of MatA
Press [SHIFT][MATRIX][7:det][SHIFT][MATRIX][3:MatA] [)] [=]

Now you want to calculate the square of matA.
Press [SHIFT][MATRIX][3:MatA] [x^2][=]
A 2x2 matrix is displayed. It is MatA[^2].

If you define MatA, MatB, MatC y

Something happened. I continue here. If you define MatA, MatB, MatC you can add them, multiply them, divide them, raise to a power, Certain operations require special conditions on the numbers of rows an number of colums. But that is part of the theory on matrices.

Solving linear equations in 3 variables by matrix method in casio fx-115ES

Press key Mode, first select option 5:EQN (by pressing key 5), then option 2: a_nX+b_nY+c_nZ=d_n (by pressin 2).
Now input coefficients from equations in table (each column is for one variable), just type in number and press =, then use arrows to move to another cell.

On which calculator can i solve 6*6 matrix

If you want to manipulate 6x6 matrices, you can use one of the CASIO Graphing calculators, such as theCFX-9850GPlus, or the FX-9750G plus.
Graphing calculators from other manufacturers can also handle such matrices. The FX-115ES can handle matrices with dimensions up to 3x3.

How do i solve a matrix?

What do you mean by "solve a matrix"? Find the inverse? Find the determinant? Find the solution to a system of linear equations? Within limits the fx-115ES can do any of these and more.

The procedures are described in the "Matrix Calculations" section of the manual. If you still have problems, please reply to this post specifying what you want to do.

How to input numbers to solve a matrix using a casio fx-115es

Press MODE 6 to get into matrix mode. Note: do this only once. If you do it again, it will erase all your matrices. Pick the matrix, set its dimension, then the calculator will put up a screen allowing you to enter/edit the matrix elements. At any time you're in matrix mode, press SHIFT 4 to bring up the matrix menu.

All this is explained in the manual beginning on page E-57. If you've misplaced the manual, you can download a copy from

How to do matrix multiplication on Casio 115ES?

Hello
First you must set Matrix calculation
[MODE][6:Matrix]. Then By entering one of the numbers [1:MatA] or [2:Matb] or [3:MatC] you get to choose the dimensions of the matrix
(mxn]. Once finished entering the matrix you clear the screen.
The operations on matrices are available by pressing [Shift][Matrix]
[1:Dim] to change the dimension of a matrix (in fact redefining the matrix)
[2:Data] enter values in a matrix
[3:MatA] access Matrix A
[4:Matb] access Matrix B
[5:MatC] access matrix C
[6:MatAns] access the Answer Matrix (the last matrix calculated)
[7:det] Calculate the determinant of a matrix already defined
[8:Trn] The transpose of a matrix already defined

To subtract MatA-MatB
To multiply MatAxMatB
To raise a matrixe to a power 2 [x2], cube [x3]
To obtain inverse of MatA already defined MatA[x-1] [x-1] is the x to the power -1 key
Dimensions of matrices involved in operations must match (see you textbook for the rules)

Hope helps

Trying to get the inverse of a matrix

Hello,

The error may be due to the key you used to signifie inverse. It says in the manual that you should use the key x^-1 not the one used to input general powers.
Here is screen capture from the Appendix to the manual. The picture shows the sequence of keys to press to obtain the inverse of a 2x2 matrix. It is taken from page 41 of Appendix

The matrix used in the exemple is
a_11=2 a_12=1 a_21=1 a_22=2
