Numberock - Addition With Regrouping Song Lyrics

Five hundred ninety-seven ants above ground
Plus nine hundred eleven ants underground
Seven plus one is eight; nine plus one is ten
Each one of them is my special insect friend
Zero stays on the floor, the hundred heads next door
The sum is getting close, so I add one once more
One plus five is six, plus nine is fifteen
My little brother thinks they're a good source of protein
We mathematicians
Add with precision
Regrouping tens or hundreds when
We find double digits in addition
One-hundred eighty-nine hens are inside
And nine-hundred eighty-five hens are outside
To find out how many hens are in the coop
We gotta know how to add and regroup
Nine and five is fourteen
Write a four, the 10 carries
One plus eight is nine, plus eight is seventeen
Keep the seven, the hundred regroups
Two plus nine is eleven, cock-a-doodle-doo
We mathematicians
Add with precision
Regrouping tens or hundreds 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 triple digit problem
Numberockers always check after we solve them
We mathematicians
Add with precision
Regrouping tens or hundreds when
We find double digits in addition
We mathematicians
Add with precision
Regrouping tens or hundreds when
We find double digits in addition
