The document outlines various rules for determining if a number is divisible by 2, 3, 4, 5, 6, 9, or 10. For each rule, it provides examples of numbers that satisfy or do not satisfy the rule's divisibility test. The rules are: a number is divisible by 2 if its last digit is even; divisible by 3 if the sum of its digits is a multiple of 3; divisible by 4 if the last two digits are a multiple of 4 or are 00; divisible by 5 if it ends in 5 or 0; divisible by 6 if it is divisible by both 2 and 3; divisible by 9 if the sum of its digits is a multiple of 9; and divisible by 10 if it ends in
