When multiplying two matrices together, you're going to go row by column, just like the order. You'll multiply the first entry in the row of the first matrix by the first entry in the column of the second matrix, then proceed along, doing this for the second entry, and so on, making a list of numbers. With the above matrix, and the first row/column, it looks like this:
$${1*1,2*3,}$$
$${1*1,2*3,3*5}$$
With the second row/column, it looks like this:
$${4*2,5*4,6*6}$$
The list is added together.
The resulting value is inserted into the cell where the row/column intercept.
%% To get answers, go through each entry in the second matrix, entry by entry, and multiply by every item in the matching row of the first one, then add all of those together. %%
