I am going to tell you how to multiply matrices.

To multiply matrices all you do is take first column of the first matrix and multiply it into the first row of the second matrix and so on and so forth.

Example: lets say you have [.4 .2] * [200] = [.4*200+.2*210] = [80 + 42] = [122]

[.3 .9] [210] [.3*200+.9*210] [60+189] [249]

First you take 200 and multiply it by .4, which is 80. Then take 210 and multiply it by .2, which is 42. Now you add these two products up which gets you 143 and that’s you’re first row of the answer matrix.

That’s how you multiply matrices.

And now you repeat the process for the second row of the first matrix.
