Question 7050
A = {{{matrix(2,2, 6,0, 1.2,-3)}}}
B = {{{matrix(2,2, 2,8, 0.6,3)}}}


A.B or whatever the notation for multiplication is in matrices gives:


{{{matrix(2,2, 12,48, 0.6, 0.6)}}}


method? there are 4 places you want to calculate. For each position, choose the row of A and the column of B that contain that position.


so for the answer 48, i had the top row of A and the righthand column of B. This gave me (6x8)+(0x3) --> 48
