Mathematics

Dear children,

How do you know whether a number is:

1) divisible by 2? --> when the ending digit of the number is even(0, 2, 4, 6 & 8)

2) divisible by 3? --> when the sum of a number's digits is divisible by 3

3) divisible by 4? --> when the number's last 2 digits are divisble by 4

4) divisible by 5? --> when the number ends in 0 or 5

5) divisible by 6? --> when a number is divisible by 2 and 3

6) divisible by 8? --> when last 3 digits of a number are divisible by 8

eg. 7168

7) divisible by 9? --> when the sum of a number's digits is divisible by 9

8) divisible by 10? --> when the number ends in 0

Thank you.

Love,
Mrs Yang
