division+rules

Yesterday we learned how take big numbers and tell if there divisible by 2, 3, 4, 5, 6.

To tell if a # is divisible by 2 you look and see if it's even or odd. If it's even the number is dividable by 2. if it's odd it's not.

To tell if a # is divisible by 3 you look at the digits add them together if you get a 2 digit # add those together until you get a one digit number if the one digit number is divisible by 3 the big # is divisible by three.

To tell if a # is divisible by 4 look at the last 2 numbers if there divisible by 4 the whole # is divisible by 4.

To tell if a # is divisible by 5 it ends in 5 or 0.

To tell if a # is divisible by 6 it follows the rules 3 and 2.
