3. Objectives:
 Divisibility rule for 11

4. Is 29601 divisible by 11?
 29601 ÷ 11
I need to check the remainder:
1. if remainder is zero then 29601 is divisible
by 11
2. If remainder is not zero, then 29601 is not
divisible by 11.

5. Divisibility rule for 11
Find the sum of the digits at odd places and
sum of the digits at even places and
Subtract them.
If the result is zero or the multiple of the 11 then
The original number is divisible by 11.

6. Divisibility rule for 11
Sum Means : to perform addition
Odd places means: All the digits in the position (1, 3 ,5, ...)
Even places means: All the digits at even positions (2,4,6,...)

7. Is 29601 divisible by 11?

8. Step 1:
Identify even and odd
places

9. Step 1:
Given number is :
Number : 2 9 6 0 1
Digit position: 1 2 3 4 5
Here, positions 1 , 3 and 5 are odd position so add all
the numbers on these positions.
2 and 4 represents even positions so calculate the
sum of digits at even places.

10. Step 2:
Sum of digits at odd places/
position:

11. Step 2:
Sum of digits at odd places= 2+6+1
Sum of digits at odd places= 9

12. Step 3:
Sum of digits at even places/
position:

13. Step 3:
Sum of digits at even places= 9+0
Sum of digits at even places= 9

14. Step 4:
Subtract two sum

15. Step 4:
Subtraction of two sum= 9 – 9
Subtraction of two sum= 0
