Mathematical Limerick ~ A Dozen, A Gross, and a Score

There are quite a few mathematical limericks in existence. This poetic form seems to 'lend itself' to a light-hearted view of the subject matter.

The limerick that I share here would be one of the better known ones that I have encountered.

Concerning its authorship, I originally wrote:
"It seems as though two or three people have been credited with creating it but the most credible source that I know of is Jon Saxon, author of the Saxon Mathematics text books. If you have more information about the origin of this limerick that you can share with me, please leave a comment."
I have since found reference on the Internet that, although the limerick appeared in one of Jon Saxon's textbooks, it was actually created by Leigh Mercer, a London wordplay artist and recreational mathematician and published in Games magazine in the 1970s. This is the same Leigh Mercer who, apparently, also created the famous palindrome, “A man, a plan, a canal — Panama!”
It helps to set the record straight.

The limerick is:

A dozen, a gross, and a score
Plus three times the square root of four
Divided by seven
Plus five times eleven
Equals nine times itself ... nothing more.

(There are variants on the last line.)

What amazes me is that, not only does it conform extremely well to the structure and rhythm of a limerick, but the mathematics is actually true! It works! I think that is a wonderful achievement.

You might like to create a mathematical limerick of your own. You will quickly discover that it is no trival matter ... but, if you succeed, I am confident that you will find the exercise abundantly rewarding.

the version i was told ended with 9 squared and not a bit more

Before adding my like, I saw this video had a total of a dozen+a gross+a score likes

Three simply-made numbers and a square
Are divided by seven as they fuse here and there
Then came eleven times five, and the great fusion comes alive
And now they all add up to a three-cube fair

I want to understand the mind of the person who came up with this. This juxtaposition of rhythm, math, and some older terminology never ceases to blow my mind.

*Thank You for Helping me know about it !!*
👍🏻✨👏

Now finally I can understand meaning of dozen now I can do my test properly

[princesspeaches]

I literally got a math homeowork to recite this in am autralian accent...i am not joking...everyone got an accent and i got australian..thank you much

[Fcutdlady]

It was on the TV show QI in the UK. Very funny

[suhanidubeyexamplayer]

Thank you so much sir for this video 👍🏻👍🏻

This helps me with my homework because it said tell Aaron 8 dozen muffins how many muffins in total did he bake know I was a little confused but I search it up and I saw this video and it might help me with my homework thanks

[spartaragekick]

i didnt no the there was a thing as a dozen system except when buying donuts...haha...

[papantro]

It can't just be me that thought a 'dozen' was an exaggeration expression with no numerical value like 'a buttload' or 'lots'. Anyway great vid!

[RebelTheArtGal]

Or you can go remove the number terms like with:

Twelve plus one-forty-four
Plus twenty plus three square root four
All over seven
Add five times eleven
Ends up nine squared and no more.
