MULTIPLICATION OF 11 WITH ANY NUMBER

Let me 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
EXAMPLE.
Here an extra case arises
Consider the following examples for that
3) 473927*11 = 4+1— (4+7-10) +1— (7+3-10) +1— (3+9-10) +1— (9+2-10)— (2+7) —7 = 5213197
4) 584536*11 = 5+1—(5+8-10)+1—(8+4-10)—(4+5)—(5+3)—(3+6)—6 = 6429896
