That's Mathematics Lyrics - Tom Lehrer

To the tune of "that's entertainment." 

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! 

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!
