There is a Professor Robbie,
who has a calculating hobby;
He delights in asking his pets,
with multiple inherent defects,
or not too brainy, to be exact.
If 2n is more or less than 2-n,
and 3x is same as 3 men, then,
the study of maths be banned.
With that Robbie will surely object,
for he makes a living on the subject;
He takes not too kindly our slow wit,
and chips away our esteem, digit-by-digit.
Equations after equations, he blast,
until one brave pet, at long last,
who sees more value in a candy bar,
than juggling numbers to solve algebra.
So Robbie, will you be ever so kindly,
spare the aging cells of these cuties,
singularly or simultaneously.
So loose no healthy slumber,
by chasing after prime-numbers;
And we who have trouble with dy or dx,
well, there is always graphic sex.
If you think this -- dX+2(x^2 - x*y^2)dy=0 -- is cool,
to make idiots out of fools,
do not be easily trapped,
into giving polite claps;
or stare at them with awe,
for they are nothing more,
than saying pluses can turn into minuses,
and at times even used as voodoo curses.
But Robbie will still caress them tenderly,
like they are his little babies,
annoying different people, differentially.
