This document outlines divisibility rules for numbers 2 through 12. For each number, it provides an example number to divide by that number and explains why the number is divisible based on the rule. The rules are: for 2, the number is divisible if the last digit is even; for 3, the digits sum is divisible by 3; for 4, the last two digits are divisible by 4; for 5, the last digit is 0 or 5; for 6, it is divisible by both 2 and 3; for 7, applying a doubling and subtracting rule on the last digit; for 8, the last three digits are divisible by 8; for 9, the digits sum is divisible by 9; for 10, the last digit
