explain this rule by taking examples
1) 234163*11 = 2---2+3---3+4---4+1---1+6---6+3---3 = 2575793
Means insert the sum of 2 successive digits and put 2 terminal digits in its place
2) 45345181*11 = 4---4+5---5+3---3+4---4+5---5+1---1+8---8+1---1 = 498796991
if sum of two digits of the number is greater than 10, then add 1 to first digit and subtract 10 to the inserted term
...................................................................
374827*11 = 3+1--- (3+7-10) +1--- (7+4-10) +1--- (4+8-10) +1--- (8+2-10)--- (2+7) ---7 = 4123097
