Diketahui matriks A = ( 5 1 ) B = ( 0 -1 ) dan C = ( -4 8) -1 -2 7 3 1 0 Matriks A - 3B + 2C adalah

A-3B+2C= (5 1) - 3(0 -1) + 2(-4 8)
               = (5 1) - (0 -3) + (-8 16)
               = (5-0+(-8)  1-(-3)+16)
               =(-3  20)

A = (5 1),  B = (0 -1),  C = (-4 8)
       (-1 -2)       (7 3)           (1 0)
A - 3B + 2C = (5 1) - 3(0 -1) + (-4 8)
                       (-1 -2)    (7 3)     (1 0)
                    = (5-3×0+(-4) 1-3×(-1)+8)
                       (-1-3×7+1 (-2)-3×3+0)
                    = (1 12)
                       (-21 -11)
