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-A-880 has last digit 0, 2^nd last digit 8 and 3^rd last digit 8.

A                                             B                                                             C                                                                             

2 X last digit                        last digit X 2^nd last digit                  2^nd last digit X 3^nd last digit

D                                             

3^rd Last digit X 4

What will be the minimum number of multiplication to multiply these matrices? Show the order of multiplication as well.
