How do you multiply three matrices given #((-1, 4, -2, 0), (3, 3, 1, -4), (0, 5, 2, -1))# and #((1, 2, 5), (-3, 4, 0), (2, 3, -4), (-1, 2, 2))# and #((-2), (4), (3))#?

To begin with matrix mult is not commutative , so the order of the mult is important.
Assuming this particular order, we start with the 3x4 and mult by the 4x3 and the resulting product will be a 3x3.
This will then be mult by the remaining 3x1 and the final product matrix will be a 3x1
