to multiply 2 matrices --> A=\begin{pmatrix}<br/>1 & 2\\<br/>3 & 4<br/>\end{pmatrix}

                                   B=\begin{pmatrix}<br/>5 & 6<br/>7 & 8<br/>\end{pmatrix}

Do the Following using ur Fx-991MS

1. Press "Mode" 3 times
2. Press "2"
3. Press "Shift"
4. Press "4"
5. Press "1"
6. Press "1"
(mXn) is the order of matrix, 'm' is asked now ; as "A" is a 2X2 matrix m=2
7. Press "2"
8. Perss "="
now the value of 'n' is asked
9. Press "2"
10. "Press "="

Now type in the values and press "=" after every value. Press "1" and then  "=" and so on for the rest. [Order: 1,2,3,4]

11. Press "AC"

Repeat the same instructions to define the matrix "B". Dont 4get to press "2" in the 6th step because its "B" matrix now.

AFter you have done defining both the matrices.

Do this to multiply them.

Press "Shift" ; "4" ; "3" ; "1" ; "multiplication sign" ; "Shift" ; "4" ; "3" ; "2" ; "="

Use the arrow keys to navigate and discover the new values in the "Answer Matrix"

Good luck.
