To do matrix multiplication in calculator Casio fx-991MS follow
the steps below:-
1] Enter in the matrix mod:-
press MODE 3 times then press 2.
2] To enter the matrix:-
press SHIFT and then 4.
press 1 to select Dim. to enter the matrix.
Suppose u hv to multiply the matri A with matrix B
then seletect A by pressing 1
chose dimension for matrix A
let m=2
so press 2 then '='
again
let n=2
so press 2 then '='
Now, enter the values in matrix
MatA11, MatA12, MatA21,MatA22
every time enter the value and then ' =' to enter another
values..
remember values get stored in the sequence of row mean
11,21,21,22
now u feel all the values of Matrix A
