1.	For matrix A, B if A – B = O, where O is a null matrix then?(a) A = O(b) B = O(c) A = B(d) None of the mentionedThis question was addressed to me in exam.I would like to ask this question from Operations on Matrices topic in chapter Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics
Answer» Right ANSWER is (C) A = B Easy explanation: If subtraction of B from A results in the null MATRIX this MEANS that A is equivalent to B.
