Will Addition and subtraction order as told by DMAS rule will be followed while solving matrices question ?
i m asking because i have seen a question where if DMAS rule is followed regarding addition and subtraction then the answer is not correct.
Yes, multiplication of matrices precedes addition. To calculate AB+C, first multiply AB then add C. If you intend that B should be added to C first, the write A(B+ C). As mr fantastic said, there is no "division" defined for matrices. First, because many matrices do not have an inverse, second, because multiplication of matrices is not commutative so even if a matrix, A, has an inverse, we could have either or while "B/A" is ambiguous. With that proviso, precedence of operations is the same for matrices as for numbers: PEMAS where I have just dropped the "M".
