A= 0 -5 10 and B = -9
-1 6 -9 0
4
Note: The order of first matrix is 2x3 (2 rows and 3columns) and that of second is 3x1(3rows and 1 column).. therefore the result matrix order is in the order 2x1
Procedure: multiplying the corresponding elements in first row of A with B then second row of A with B. i.e.,
AB= (0x-9)+(-5x0)+(10x4)
(-1x-9)+(6x0)+(-9x4)
AB= 40
-27
