Hey @promisechi!

You might want to look at bounties to get people to make code for you.

Well, you can try below code for multiply a matrix.

DIM A(3, 3), B(3, 3), C(3, 3)

' Input values for matrix A
PRINT "Enter values for matrix A:"
FOR i = 1 TO 3
    FOR j = 1 TO 3
        INPUT "A(" + STR$(i) + "," + STR$(j) + "): ", A(i, j)
    NEXT j
NEXT i

' Input values for matrix B
PRINT "Enter values for matrix B:"
FOR i = 1 TO 3
    FOR j = 1 TO 3
        INPUT "B(" + STR$(i) + "," + STR$(j) + "): ", B(i, j)
    NEXT j
NEXT i

' Multiply matrices A and B to get matrix C
FOR i = 1 TO 3
    FOR j = 1 TO 3
        C(i, j) = 0
        FOR k = 1 TO 3
            C(i, j) = C(i, j) + A(i, k) * B(k, j)
        NEXT k
    NEXT j
NEXT i

' Display the result matrix C
PRINT "Resulting matrix C:"
FOR i = 1 TO 3
    FOR j = 1 TO 3
        PRINT C(i, j);
    NEXT j
    PRINT
NEXT i

END

Thanks
