This is what too much mathematics does to you.

X is a magic variable
Yes it is, its a magic variable
Somewhere in that ancient mystic xity
You'll get x
As a magic variable
The past and the present and the future,
Faith and hope and charity,
The heart and the brain and the body,
Will give you x
Its a magic variable

It takes x legs to make a xpod or to make a table stand,
And it takes x wheels to make a vehicle called a xicle
Every xangle has x corners,
Every xangle has x sides,
No more, no less,
You dont have to guess
When it's x
You can see?
It's a magic variable

A z and a y had a little q
Yes they did
They had x in the family
And thats a magic variable

x, 2x, x^2,
4x, 5x, 2x^2,
7x, 8x, 3x^2,
10x

Now multiply backwards from x times 10
x times (3x+1) is 10x
x times 3x is 2x^2
x times 8 is 8x
x times 7 is 7x
x times 2x is 2x^2
x times 5 is 3x
x times 4 is 4x
And x times x is x^2
And x times 2 is 2x
And x times 1 is x of course
(now dig the pattern once more!)

x, 2x, x^2,
4x, 5x, 2x^2,
Oh yeah

x times (3x+1) is 10x
x times 3x is 2x^2
x times 8 is 8x
x times 7 is 7x
x times 2x is 2x^2
x times 5 is 3x
x times 4 is 4x
And x times x is x^2
And x times 2 is 2x
And x times 1
What is it?
x

That's a magic variable

A z and a y had a little q
Yes they did
They had x in the family
That's a magic variable
