Unless otherwise instructed, perform the indicated operations on these matrices. So for two matrices to be equal, the dimensions must be the same and the numbers/variables must be in the same position.This second video explains matrices and some basic operations in more depth with plenty of examples.Unlike with addition, multiplication of two matrices is quite involved and the technique is somewhat counter-intuitive.
