Here are a few math limericks. Taken, by permission, from

		An algebra teacher named Drew
		tried to find the square root of 2
			he found it between
			a quarter and 14,
		but couldn't get closer. Can you?
		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.
		A mathematician confided
		that a Möbius band is one-sided.
	  		and you'll get quite a laugh
	   		if you cut one in half,
		for it stays in one piece when divided.

		A dozen, a gross, and a score,
		plus three times the square root of four,
	   		divided by seven,
	  		plus five times eleven,
		equals nine squared and not a bit more.

		'Tis a favorite project of mine
		a new value of pi to assign.
	   		I would fix it at 3
	 		for it's simpler, you see,
		than 3 point 1 4 1 5 9.

		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.
