 0  2    x   6  -6  =        6     0

-2  -5       3   0            -27 12

 

 

this is a     2 x  *   1 x 2    so result should be  2 x 2  (the red numbers)    we can see this is an allowable multiplication because the green numbers are the same.

 

6     *    -5  4    =   -30   24

-3                           15   -12
