I don't need a calculator
I'll just use a piece of paper

This may take a while
So I'll see you later

You say you want sum (It doesn't add up)
You say you need sum (It doesn't add up)
You gotta have it

On top of me like a numerator
Bringing me down to the denominator

Always rubbing your eraser
You turned out to be a number hater

You say you want sum (It doesn't add up)
You say you need sum (It doesn't add up)
You gotta have it

What are you talking about?!
