The Math Song Lyrics

Spoken by a sampled voice:

"Your facts! Your figures! What are they worth now, huh? Are they worth the lives of seven billion people!?"
Sung:

y, y equals x over five
Five to the power of xi
Xi is the square root of three
Three is the number for me

I said x
X by the tangent of n
And, minus Pi over ten,
That equals negative nine
Negative nine is so fine

You've got a brain
And nobody really needs another love song, love song
You've got a brain
And nobody really needs another love song, love song
You've got a brain
And nobody really needs another love song
N
N is the product of v
V and the cosine of three
Cube that and add forty-four
And not an integer more

Baby, V
V equals one through the sum
The sum of one hundred and one
And eighty-three over five
What is the value of y?
You've got a brain
And nobody really needs another love song, love song
You've got a brain
And nobody really needs another love song, love song
You've got a brain
And nobody really needs another love song, love song
You've got a brain
And nobody really needs another love song

You've got a brain
And nobody really needs another love song, love song
You've got a brain
And nobody really needs another love song, love song
You've got a brain
And nobody really needs another love song, love song
You've got a brain
Yeah I heard you've got it
