        Topic Notes
        Had enough of listening to rules at home and at school? Well, we promise we won't give you too many! In this section, we will be using a set of divisibility rules to find the factors of whole numbers. These divisibility rules allow us to determine whether a given number is divisible by numbers two through ten by examining the digits of the number.
