Read the following statements about matrix operations: (i) Addition of two matrices is possible only when they have the same dimensions. (ii) Multiplication of two matrices AB is possible only when the column dimension of matrix A is equal to the row dimension of matrix B. (iii) If matrix A has dimensions m × n and matrix B has dimensions p × q with n = p, the order of matrix AB will be n × q. Which of the above statements are correct?
