Special Divisibility Rule of '' 11 ''

Divisibility Rule of "11":
SPECIAL RULE:
 The special divisibility rule of 11 is successive subtracting the digit values from previous digit place it start from the last digit 
For Example:
                   (1) 1342
last digit from the above number is 2 subtract from the previous digit value =134-2=132
Repeat once last digit of 132 is 2 subtract from 3 
                   =13-2=11
From the above answer 11 it is divisible by 11
Therefore, the whole number is divisible by 11

First Rule:
To verify the divisibility rule of 11, the subtracted value from the sum of even digits place value to sum of odd digits place value is divisible by 11 then the whole number is divisible by 11
For Example:
        (1)1342
sum of the even place digits value = 3+2=5
sum of the odd place digits value = 1+4=5
subtract both=5-5=0 
If the any divisibility we get " 0 " as your answer then it obey's your divisibility rule
       (2) 29435417
sum of the odd place digits value = 2+4+5+1=12
sum of the even place digits value=9+3+4+7=23
subtract both=23-12=11 
on the sight the result is divisible by 11
Then the given number is divisible by 11
