Best ResponseYou've already chosen the best response.1Here you go (the first problem is last, because I thought it was a division sign!) http://postimage.org/image/kmf3y8d8n/

Best ResponseYou've already chosen the best response.0why is the third problem not possible?

Best ResponseYou've already chosen the best response.1Because the two matrices are of different dimensions. If you go ahead and try to attempt it, you'll see quickly that you've run out of numbers and have two left over. It simply doesn't work. =)

Best ResponseYou've already chosen the best response.0the 6th question there is no "" or " + " so i think we can not operate it?

Best ResponseYou've already chosen the best response.1That would assume that you multiply them.

Best ResponseYou've already chosen the best response.0but it is set like this [ 1 2 ][1] [3 7] [5]

Best ResponseYou've already chosen the best response.1It's uploading! You can only multiply matrices if the rows of the first equals the columns of the second. Basically, how that works is you take the terms as such: [ a b ] [1] [ c d ] [5] so that the new matrix is: [ a*1 + b*5 ] [ c*1 + d*5 ]
