Divisibility+Rules

Yesterday in class we learned that there are "tricks" or "rules" to dividing. We learned the divisibility for the numbers 2,3,4,5, and 6. The rule for 2 was pretty simple: any even number can be divided by 2.

3 was a little harder. If you add up all the digits (example: for the number 1,203 add 1+2 +3 and you will get 6,so 3 is a multiple of 6 so you can divide it by 3).

4 right now we are having technical difficulties and I can not remember

5 is simple any number that ends in 5 or 0 can be divided by 5.

6 right now we are having technical difficulties and I can not remember
