Matrix

 0  2    x   6  -6  =        6     0

-2  -5       3   0            -27 12

this is a     2 x 1   *   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

thank you wold the 1st row 1st column element be "6"?

much appreciated!
