Lyrics:

Twelve plus nine is twenty one
Adding up numbers is very fun
Seven plus eight equal fifteen
Adding up numbers is very uplifting

Adding up numbers
Adding up numbers

Nine plus zero is equal to nine
Even adding nothing is adding just fine
Twelve plus ten is twenty two
Carrying the one is easy to do

Twelve plus nine is twenty one
Adding up numbers is very fun
Seven plus eight equal fifteen
Adding up numbers is very uplifting

Adding up numbers
Adding up numbers

Two plus five is equal to seven
Add four more and you get eleven
Five and three are equal to eight
Adding up numbers makes you feel great

Twelve plus nine is twenty one
Adding up numbers is very fun
Seven plus eight equal fifteen
Adding up numbers is very uplifting

Adding up numbers
Adding up numbers

Adding up numbers
KOMPRESSOR adding up numbers
Adding up numbers
KOMPRESSOR adding up numbers
