I have some geometry homework and I need help. 

How do you multiply a regular number by a matrix? 

For example: 5[3/-1] 

Please explain matrices in general as I have no idea on the subject.

Just multiply each entry in the matrix by the number.....example

 

 

3 [ 1   2  ]   =    [ 3   6  ]

   [ 6  10 ]         [18 30 ]
