Thirty-seven ants above ground
Plus forty-three ants underground
Seven plus three equals ten
Each one of them is my special insect friend
Zero stays on the floor
The ten heads next door
The sum is getting close
So I add once more
One plus three is four
Plus four is eight
My little brother thinks they would taste great
We mathematicians
Add with precision
Regrouping tens when
We find double digits in addition
Twenty-Nine hens are inside
And fifteen hens are outside
To find out how many hens are in the coop
We gotta know how to add and regroup
Nine plus five equals fourteen
Write the four; the ten carries
One plus two is three
Plus one is four
I wish the farmer was an herbivore
We mathematicians
Add with precision
Regrouping tens when
We find double digits in addition
Sometimes we make errors, it's inevitable
But check your work and it'll be indubitable
The best way to check your addition is by subtraction
The inverse operation
Take either addend
And subtract from the sum
If you get the other addend
Your work is done
When presented with a double digit problem
Numberockers always check after we solve 'em
