2+1 Math Rocks! - Divisibility Lyrics

These are rules for divisibility
These are rules you divide with ease
Let's start with the number 2
Goes into even numbers yes it's true
Number 5 is easy can't you see
Ends in a zero or a 5 it's free
Number 10 has just one rule
Ends in zero, yeah you know that's cool
It seems these rules are easy now
There are more rules
I'll show you how
Dividing never seemed to be so easy

These are rules for divisibility
These are rules you divide with ease
In this song you'll remember rules
Who'd have thought learning is so cool

Let's try the number 3
Add the digits up and then you'll see
If the total is a multiple of 3
Then you have divisibility
Number 4 is not a chore
Last two digits really tell the score
If they are a multiple of 4
That's a rule for 4 you can't ignore
It seems these rules are easy now
There are more rules, I'll show you how
Dividing never seemed to be so easy

These are rules for divisibility
These are rules you divide with ease
In this song you'll remember rules
Who'd have thought learning is so cool

Here's a rule for the number 9
Add the digits, yeah you're doing fine
If the total is a multiple of 9
Like the 3 you have divisibility

These are rules for divisibility
These are rules you divide with ease
In this song you'll remember rules
Who'd have thought learning is so cool
