Divisibility Rules for 6, 9 and 10

This video tutorial covers the rules for determining if a whole number is divisible by 2, 3, 6, 9, and 10. It explains that a number is divisible by 2 if its last digit is even, by 3 if the sum of its digits is divisible by 3, and by 6 if it meets both conditions for 2 and 3. For divisibility by 9, the sum of the digits must be divisible by 9, and for 10, the last digit must be 0. Examples are provided for each rule to illustrate the concepts.
