Given #A=((-1, 2), (3, 4))# and #B=((-4, 3), (5, -2))#, how do you find A-2B?
Follow the order of operations to find:
To solve a matrix equation we follow the normal order of operations with the added restriction that multiplication and division need to happen in the order that they are written, since for matrices,
So for our equation,
subtracting two matrices requires that each matrix have the same dimensions - this is true in our case since
in our case
