2)

B  = 2 x 2     C =  2 x 3

So

B * C  =      [ 2 x 2 ] * [ 2 x 3 ]      the "inner" dimensions are the same  so the result will be the "outer" dimensions  =

2 x 3  =  2 rows  and 3 columns

So  we have

[ -4  2  ]         x      [ 0  4  -1   ]     =          [ (-4 * 0 + 2 * 3)   ( -4*4  + 2*0)   ( -4*-1 + 2*1)  ]   =

[  0  5  ]                 [ 3   0   1  ]                  [ ( 0*0 + 5*3  )      (0*4 + 5*0)     ( 0*-1 + 5* 1)  ]

[  6   - 16    6  ]

[ 15     0     5  ]

For the first part.....I believe  "m"  = 16/3

But....I don't understand the second part of the question, at all....I haven't seen something like this before
