Here is enough to get you started and a little more.

Read
the post ant consult your calculator manual. The screen captures below
may not look exactly as your calculator but the steps are identical.**A. Define a matrix (Create it)**

- Turn calculator ON.
- Press Menu,select the MAT icon and press [EXE]
- You see a list of possible matrix labels (A, B, C,D,E,F)
- All that have not been created have a "none" to their right
- Highlight a matrix name and press the right arrow. Where there was "none" , you have a template 0x0.
- That is where you specify the dimensions (mxn). example. 2x2
- Enter the first dimension and press [EXE]
- Enter the 2nd dimension and press [EXE]
- A matrix template opens where you enter the coefficients left to right and up down.
- After each coefficient press [EXE]. Cursor moves to the next coefficient, etc.

Once you have one matrix, you can do operations on it: Calculate the determinant (if matrix is square), calculate its inverse, transpose, augment it, fill it, etc..

- These operations are accessed as follows.
- Quit the matrix editor by pressing [Menu] and selecting the [Run] application.
- Press [OPTN][F2:MAT]
- You have the menus Mat,M(atrix)->L(ist), Det(erminant), Trn (transpose), Aug(ment) ->, Iden(tity),Dim(ension) Fill

- You press the [OPTN][F2:MAT] key sequence (just above)
- Press [F3:Det]; the command
**det**is displayed on screen. - Press [F1:Mat] the identifier
**Mat**is displayed. - Press [ALPHA] A; screen display
**det Mat A**. - Press [EXE] to get the value of the determinant.

[OPTN][F2:MAT] (MAT) [Alpha] A ^2 [EXE]

D. Product of two compatible matrices MatAXMatB

[OPTN][F2:MAT] (MAT) [Alpha] A [*] (MAT) [ALPHA] B [EXE]

Part E Invert a (square, non singular) matrix that was already defined.

Press [OPTN] [F2:Mat] to open a screen similar to the one in capture above

Press [F1:Mat] to have identifier Mat displayed.

Enter the name of the matrix by pressing [ALPHA] A, for example.

Press [SHIFT] [ ) ] activate the (x^-1) key.

This is what you might see (with parentheses and without).

Press [EXE] button to calculate the inverse.

The Casio FX-570MS does not handle matrices. So you cannot create matrices, let alone invert them. Sorry.

The Casio FX115 ES handles matrices for up to 3X3 dimension. Create the matrix.Have its name displayed on the command line and press the [x^-1] (reciprocal ) key.

The enclosed screen capture shows all the possible dimensions for matrices on the Casio FX-991ES. As you can see the maximum dimension of any matrix is 3. You can only create matrices with dimensions less than or equal to 3.

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.

No, it does not. You will need a graphing calculator such as the Casio FX-9750G Plus or the newer version FX-9750 GII.

Calculator should be in [MATRIX] MODE

Try the matrices 2X2 matrices matA [1,2,3,4] matB [5,6,7,8], Add them, subtract them, multiply them, take the square of each. If that works for these matrices, then it must be your data. Be careful with negative numbers. To enter those, you must use the change sign (-).

There is also the possibility that the instructions were misread.

Hello,

If by calculus problem you mean derivatives of functions, integrals, extrema and such things, I am sorry to inform you that neither the Casio FX-300MS, nor the FX-991MS can handle them. The newer Casio calculator FX-991ES is capable of performing numerical differentiations and integrations. There also graphing calculators by Casio FX-9750G, FX-9860G as well as by Texas Instruments (TI 83 PLUS/TI84PLUS) that are reasonably performant in that area.

Hope it helps.

Hello,

Turn calculator ON. You should see several icons. Use the arrows to highlight the RUN icon. Press [EXE], the screen clears and you are left with a blinking cursor. Now you are ready to start using the basic functions (add, subtract, multiply, etc.). But if you want to do more and pay tribute to the huge capabilities of your calculator, you should take a look at the manual.

Here is the link to all chapters..
