Question 94292
Given these matrices and their dimensions: A 3x2, B 3x2, and C 2x4 Which of the following can NOT be performed? 

Adittion and subtraction of matrices.

Addition or subtaction of matrices between two matrices is possible if the order of the two matrices are same.

(A+B ) or (B+A) is possible as the oder of the two matrix is the same,that is 3x2

(A-B) 0r (B-A) is possible as the oder of bothe matrix is same,that is 3x2

now  addition or subtraction of matrix is not possible between A and c or B and c, as their orders are different i.e A = 3x2, b = 3x2 and c= 2x4


Multiplication od matrix

Two matrix can be multiplied when the column of the first matrix is equal to row of the second matrix

Here,

AxB is not possible as the column of A= 2 and row of B = 3 , they are not equal.

BxA is not possible as the column of B = 2 and row of A = 3 , they are not equal.

AxC is possible  as the column of A = 2 and row of C = 2, they are equal

CxA is not possible as the column of C = 4 and row of A = 3,they are not equal.

BxC is possible as the column of B = 2 and the row of C = 2, they are equal.

CxB is not possible as the column of c = 4 andthe row of B = 2, the are not equal.
