Calculus

‘The perfect number is a positive integer that is equal to the sum of its proper divisors’

I did count out what I have done for you,
now you to count what you’ve done too.
My fag-packet relative comparisons,
reveal to me necessary adjustments:

Upsetting a child is a minus of your sum.
Putting down one’s own is long division.
Disparaging of men, is a simple add-on.
Not offering compassion is a multiplication.

And your friends complain of your equations,
dead-reckoning now with their own estimations,
they live quite well,  with your bone-dry worth,
but only if their values are not reversed.
