Multiplication of Any Number by 11

Multiplication of Any number by 11

Rule :-
         •Place Zeros before and after given number .
         •Go on adding  the neighbouring numbers until all later zero is encountered .

Consider following examples :-

Example 1:-
      13 ×11 =???
            Step1 :- 0130
            Step2 :- (0+1)/(1+3)/(3+0)
            Step3:-1/4/3
  Therefore , 13×11 = 143

Example 2:-
        123×11 = ??
               Step1:- 01230
               Step2:- (0+1)/(1+2)/(2+3)/(3+0)
               Step3:- 1/3/5/3
     Therefore,  123×11 =1353

Example3:-
        258 ×11 =??
              Step1:- 02580
              Step2:- (0+2)/(2+5)/(5+8)/(8+0)
              Step3:- 2/7/13/8
              Step4:- 2/(7+1)/(3)/8
    Therefore,  2838
Example 4:-
                    786 ×11 =??
             Step1:-07860
             Step2:- (0+7)/(7+8)/(8+6)/(6+0)
             Step3:- 7/15/14/6
     
  Note:-If the number in each block is greater than 10 then transfer to next block.
   Therefore,   786 ×11 =8/6/4/6
                           786×11 = 8646.

It is simple.
