input issues

How can I make a Matrix like nxm size and then fill the places with my own variables, then to operations between 2 Matrices and print them out. I went with Help but when I try it like this;

Code:

LOCAL A1,A2; /// A1=B, A2=Cl
A1:=MAKEMAT(0,2,2)→[[b11,b12],[b21,b22]];
A2:=MAKEMAT(0,2,2)→[[c11,c12],[c21,c22]];

It throws an error in this field "→" Is there another symbol that i can use in notepad when writing programs?

Will it function as a matrix if I write it like this:

Code:

LOCAL A1,A2; /// A1=B, A2=Cl
A1:=[[b11,b12],[b21,b22]];
A2:=[[c11,c12],[c21,c22]];

[/code]

It seems it works also you can print by row
PRINT=(""+A1(1)); - Prints first row of matrice A1

EDIT: How will I extract value from matrix A2 that is a product of A2:=A1*A2 ?
I need values of A2 [a11,a12], [a21,22] etc...
