2. Now we need to Define matrices and set its dimensions.
   This product supports matrix of order up to 3x3. That is you can operate matrix of No. of rows=3 and No. of columns=3
   To input matrix, Press SHIFT and then 4. This will Pop up Menu for Matrix. Now press 1
   Your screen will show as this,
   
   MAT A will be your First Matrix and MAT B will be your Second Matrix and so on.

4. On Next Screen , enter values on each positions
   
   Press UP, DOWN, LEFT, RIGHT Keys to move around in matrix and specify each element.
   
   
5. Now we inputed Details about Matrix A. If you want to specify other matrices (MATRIX B, MATRIX C) repeat STEPS 2 To STEP 4
   
   
   
6. After Specifying required Matrices, we can tell calculator to do operations with them.
   
   Press SHIFT and then 4 and then It will show a menu contains
   
   
   
7. For example, i need to multiply Matrix A with Matrix B, i'll enter as
   
   SHIFT + 4 + 3 to Input Matrix A
   
   X to enter operator (Here multiplication, You enter + - x / for corresponding arithmetic operations )
   
   SHIFT + 4 + 4 to Input Matrix B
   
   = To show Result
   Press UP DOWN LEFT RIGHT Keys to view extra fields, if any.

have a good time with Casio FX 991ES

It is just a matter of being in EXACT mode. To set your calculator in EXACT mode here's the key sequence. Press [MODE] [F3] [Up Arrow] [Up Arrow] [Right Arrow] [2] [ENTER]. Now when your in the Matrix Editor you can input your numbers in decimal form and, they will be automatically be converted to a fractional format. Pictured below is a matrix that was entered using decimal numbers and, was converted into factional form. Notice at the bottom of the screen the calculator is in EXACT mode.


Here's the same matrix in the HOME screen.



Next is the same matrix converted back to decimal numbers. Notice at the bottom of the screen the calculator is in APPROX mode.



And of course when I turn the calculator back to EXACT mode and, Re-ENTER the decimal formatted matrix in the HOME screen the fractional formatted matrix reappears.

You can use the propFrac( command but, having in the EXACT mode setting works better.

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

To compute the tangent of an angle, press TAN and enter the angle. Make sure you have the appropriate angular mode (radians or degrees) set first.

Press MODE 6 to get into matrix mode. Once in matrix mode, SHIFT 4 will bring up the matrix menu for further operations. Be careful and don't press MODE 6 again or it will erase all your matrices. To get out of matrix mode, press MODE 1.

You need to uninstall and remove all temp files then do a fresh install. Sounds like one or two of the dll files are corrupted

In any scientific calculator log2(n) can be  calculated with either ln or log function as follows
 
Log2(n)= ln(n) / ln(2)
 
Or
Log2(n)=log(n) / log(2)

both will give nearly the same answers
