Multiply these matrices by hand


 * 2 3| *|3 9|
 * 4 9| |6 7|

When multiplying matricies, as you go down a column, in which direction do you go through the row? Which pair of dimensions are able to be multiplied?: 2x2 and 3x4...4x3 and 3x6

I assume this is two matrices.


 * (2*3)+(3*6) (2*9)+(3*7)|
 * (4*3)+(9*6) (4*9)+(9*7)|


 * 24 39|
 * 66 99|
