Letra de That's Mathematics de Tom Lehrer

counting sheep
when you're falling asleep,
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 recipee 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'd 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!
