1. There once was a student in school,
Who couldn't do math as a rule,
He worked at it a lot,
Till each answer he got,
And now he's no longer a fool. (Meryl Altabet)
2. An algebra teacher named Drew,
Tried to find the square-root of 2.
He found it between
1/4 and 14,
But couldn't get closer. Can you?
3. There once was an old man named Drew,
Who wanted to know how to add two and two.
“I think more and more
That it makes about four
But I fear that is almost too few."
4. There was a young lady called Kate,
Whose math was right up-to-date.
She said, "It is fun
When three 3's are one
Which they are with modulo 8."
5. There was a young student from Rye
Who worked out the value of pi .
"It happens," said she,
"That it's just over 3,
Though I'd rather you don't ask me why."
6. Little Jack Horner sat in a corner,
Trying to evaluate pi .
He disclaimed rule of thumb,
Found an infinite sum,
And exclaimed "It's real, nary an i."
7. A graduate student at Trinity
Computed the square of infinity.
But it gave him the fidgets
To put down the digits,
So he dropped math and took up divinity.
8. A mathematician named Boole,
Used to mispronounce words like a fool.
He spoke of "stastistics",
And "intragel" ballistics,
"Yuler" circles and "Hospital's" rule.
9. There was a young student from Crewe
Who learned how to count in base 2.
His sums were all done
With 0 and 1,
And he found it much simpler to do.
10. There was a young fellow called Dan,
Who knew all about sin, cos and tan.
He talked rather big
Of his knowledge of trig
But he couldn’t even open a fan.
11. Integral z-squared dz
from 1 to the cube root of 3
times the cosine
of three pi over 9
equals log of the cube root of e. (from Zero Gravity)
12. The integral from e-squared to e
Of 1 over v dot dv
When raised to the prime
Between 5 and 9
Is e to the i pi 
by 3. (M. M Bishop)
13. There once was a number named pi
Who frequently liked to get high.
All she did every day
Was sit in her room and play
With her imaginary friend named i. (Eve Andersson)
14. There once was a number named e
Who took way too much LSD.
He thought he was great.
But that fact we must debate;
We know he wasn't greater than 3. . (Eve Andersson)
15. There was a math student called Hector,
Who couldn't tell scalar from vector.
"I'm quite at a loss
To tell a dot from a cross -
I ought not to work in this sector."
16. There once was a number pi
Very special like e and phi.
Circumference to d
Is the ratio for me
And it's not a multiple of i. (Liz Landau)
17. A conjecture both deep and profound
Is whether the circle is round.
In a paper of Erdös
Written in Kurdish
A counterexample is found.
18. There was a young lady named Bright
Whose speed was much greater than light.
So she set out one day,
In a relative way
And returned on the previous night. (George Gamov ?)
19. A wonderful bird is the pelican;
His beak
can hold more than his belly can.
He puts in his beak,
Enough food for a week.
Nobody knows how the [censored] he can. (Old standard example of a limerick)
20. There
once was
a girl from
Who had a most beautiful [censored].
Not smooth and round and [censored]
As most of you might think
It was grey, had long ears, and ate grass. (from Isaac Asimov’s book ?)
21. There once was a function of x
With deplorable notions of [censored].
In half-Baire condition
It attempted [censored]
With a function weakly-complex. (Some [censored] mathematician)
