What is the divisibility rule for 11, 12, and 13?
Please see below.
Mark off the digits in groups of three starting from the right (just like we do when we put commas in large numbers).

The divisibility rule for:
-
11: Add the digits in odd places and then the digits in even places. If the difference between the two sums is divisible by 11, then the whole number is divisible by 11.
-
12: A number is divisible by 12 if it is divisible by both 3 and 4. To check divisibility by 3, add up the digits of the number. If the sum is divisible by 3, then the number is divisible by 3. To check divisibility by 4, examine the last two digits of the number. If the number formed by the last two digits is divisible by 4, then the whole number is divisible by 4.
-
13: There isn't a simple and widely known rule for divisibility by 13. Divisibility by 13 is usually checked by division.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
