Song: That’s Mathematics


Counting sheepWhen you're trying to sleep,Being fairWhen there's something to share,Being neatWhen
you're folding a sheet,That's mathematics!
When a ballBounces off of a wall,When you cookFrom a recipe book,When you knowHow 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 chooseHow much postage to use,[]When you knowWhat's the chance it will snow,When you
betAnd you end up in debt,Oh try as you may,You just can't get awayFrom mathematics!
Andrew wiles gently smiles,Does his thing, and voila!Q.e.d., we agree,And we all shout hurrah!As he
confirms what FermatJotted down in that margin,Which could've used some enlargin'.
Tap your feet,Keepin' time to a beat,Of a songWhile you're singing along,HarmonizeWith the rest of
the guys,Yes, try as you may,You just can't get awayFrom mathematics!
