hey...can someone tell me the division rules like i know that 3 is just add the diggits and see if divisible by three...but i cant remember the rest...im in pre algebra...i suck at this math stuff lol=U

two if its even (duh)
3-yeah add up the digits and divisble by three
4-if if the last two digits are multiples of four--ex-448-yes becuase 4 can go into 8
5-not hard to figure out
6-do the three one and then make sure on calculator
for the rest just use a calc and if u cant take ur time and figure it out

2-if 2 is divisible by the last number
3-add all the numbers together and if the sum of the digits is divisible by 3
4-its the last two digits are divisible by 4
5-if the last digit is 5 or 0
6-if 2 and 3 can go into the number
9-same as three except that its if 9 can go into it
10-if the digit is 0
