For the sake of eligibility
I used to enjoy being precise
But since it got me in a fix
I just stuck with being nice
“You don’t even know your own phone number”
Something I no longer say, although
0 (oh) is not a number
Try a nought, or a zero
Zero is a magnitude, not a number
It represents an empty quantity
It may have little value to you
But in mathematical terminology…
…Nought is the one and only additive identity
Added, it leaves anything unchanged
Rational, real and complex numbers
No matter how they’re arranged
Multiplying by nought, has the result nought
A quite unique mathema-magic trick
And consequently, dividing by nought
Has no meaning, in arithmetic
Without a thought
Nought was bought
Whole numbers, v natural numbers
Both infinite series, just grow
But you can still take one from another
Leaving you with a perfect zero
