Q.No.1: Consider the following chain of matrices having matrices A, B, C and D. You have to consider the digits of your Registration Number in the order of the matrix as given. Add 2 to the digit if its zero.
For example, your Reg_No. 19-Arid-797 has last digit 7, 2nd last digit 9 and 3rd last digit 7.
A B C
2 X last digit last digit X 2nd last digit 2nd last digit X 3nd last digit
D
3rd Last digit X 4
What will be the minimum number of multiplication to multiply these matrices? Show the order of multiplication as well.
