Tom Lehrer
That’s Mathematics
Counting sheep
When you're trying to sleep
Being fair
When there's something to share
Being neat
When you're folding a sheet
That's mathematics!

When a ball
Bounces off of a wall
When you cook
From a recipe book
When you know
How much money you owe
That's mathematics!

How much gold can you hold in an elephant's ear?
When it's noon on the moon, then what time is it here?
If you could count for a year, would you get to infinity
Or somewhere in that vicinity?

When you choose
How much postage to use
When you know
What's the chance it will snow
When you bet
And you end up in debt
Oh try as you may
You just can't get away
From mathematics!
Andrew Wiles gently smiles
Does his thing, and voila!
Q.E.D., we agree
And we all shout hurrah!
As he confirms what Fermat
Jotted down in that margin
Which could've used some enlargin'

Tap your feet
Keepin' time to a beat
Of a song
While you're singing along
Harmonize
With the rest of the guys
Yes, try as you may
You just can't get away
From mathematics!
