This is my math test about divisibility rules. I was pretty confident going in to the test, and I only made one silly mistake.

2-- the ones collum must be even.

3-- add up all the digits in the number and if the sum adds up to be a multiple of 3 then it is divisible by 3. eg,

591 5+9+1=15 divided by 3=5

I've learned up to 10 except for 7, people never really figured that number out.
