This parody song was written and performed in 2012 for the retirement of my BSU colleague Professor Tom Moore – number theorist, mathematical problem-solver extraordinaire, and a pillar of the Bridgewater mathematics department for more than forty years.

### Numbers That I Used to Know

##### in the style of “somebody that i used to know” (Gotye)

*Student:*

Now and then I think about my calculator

Bought it for a hundred bucks in junior high

That TI-83 was my best friend

I thought I’d be with it until the end

But now in college I’m a mathematics major

Nowadays I don’t have use for computation

And every question asks me why — I don’t know why

I used to think that one and one was two

But now I’m not sure even that is true

It at the very least depends on your definitions

**Chorus:**

My teachers only showed me how

To plug in numbers to a formula and get an answer

Calculation’s great and all

But what good is a decimal without a point?

It’s such a mindless plug-and-chug

Calculator did my work without me even thinking

That’s not mathematics, though

Those were just the numbers that I used to know

*Teacher:
*Now and then I think of all my amazing students

So good at memorizing just how every problem must be done

Got the answers right on their first try

They didn’t ever ask me why

So just take your A-plus and go

There’s no more to mathematics than the numbers that you used to know

*Student:
*You didn’t ever justify

Told me everything was true because the textbook said so

I don’t have to take your word

‘Cause everything’s conjecture ’till you have a proof

First principles and axioms

Implications, propositions, theorems, corollaries

That’s how mathematics goes

It’s more than just the numbers that you used to know

More than just the numbers that you used to know
