dw:1347303006293:dw matrix multiplication is performed as : for 1st element u multiply corresponding elements of 1st row of 1st matrix and 1st column of 2nd matrix and then adding all of them., as shown. so u had BA right ? first row of B was 3,6,3 first column of A was 1,2,2 multiplying and adding, we get : 3*(1)+6*2+3*2 = 15 thats how i got 15... does this make some sense to u ??
