Pengurangan Matriks

Jika Amxn  = (aij) dan Bmxn = (bij) ,maka A mxn – Bmxn = Cmxn =(cij), (aij) = (bij),

Contoh:

A =                                       B =                     , maka  A + B =

2     1                                             -2     4      , maka   A + B =     2       1         –        -2       4    =       4      5    = C = (cij)

3     2                                              3      2                                            3        2                     3       1             0      1

A =                                                 B =

3       2        1                                         2       7      -2     ,

-2       3        4                                         3     -5        1

maka  A + B =

3        2         1        –         2        7        -2      =      1        -5         3      = C (cij)

-2        3          4                  3       -5        1              -5         8         3
