MATLAB makes these things really easy:
>> A = [
     4     8     6
     3     5     7
     1     9     2];
>> B = [
     7     8     4
     5     2     4
     1     7     9];
>> A + B
ans =
    11    16    10
     8     7    11
     2    16    11
Note that it would probably be a bad idea to create three separate variables: programming is easiest when you keep your data together as much as possible (e.g. in one array, like I show), because then you can loop and apply to functions to an entire array.
