JShippersAsked to answer + 1 comment Matrix multiplication - not elementwise multiplication aka Hadamard product. Clue, Entry (1,1) in the final matrix = 18.

NotAnAmbiTurner + 1 comment I still don't get it :(

JShippers + 1 comment To multiply matrices A = {{a11,a12},{a21,a22}} and B = {{b11,b12},{b21,b22}}, the new matrix is of size 2x2, and the top left entry = ((a11 x b11) + (a12 x b21)), the top right entry = ((a11 x b12) + (a12 x b22)), and so on.. I recommend watching a youtube video or something, I can't give the answer...

NotAnAmbiTurner + 0 comments ok, thanks. I watched something on Khan Academy that explained it well.
