Divisibility A-Go-Go

Listen, young friends

                      and you will soon learn

Some divisibitliy rules

                      of three numbers in turn

Now to tell if a number

           is divisible by two

A very quick glance

           is all you must do

Cause if your number

           be it small or great

Has an ending even digit

           (0,2,4,6, or 8)

Then this is the clue

           that it is divisable by two!

Now to tell if a number

           is divisable by three

You must add up the digits

           of the number you see

Then divide by three

           this digital sum,

And if you get an answer

           but a remainder doesnt come

Then this is the key

           that the original number

Was divisible by three

Now to tell if the number

           is divisable by five

A very quick trick

will put you in the jive

For if your number

ends with zero or five

Then you've got it cooled _

you're awake and alive

As this little number

is divisable by five

And so young friends

by now you should know

Some modern math rules
