Odd poem: Mathematical limerick by Leigh Mercer

That may not look like a limerick to you, but if you read correctly it can be!

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

Leigh Mercer was a very odd character. Born the son of a Church of England pastor in 1893, he said “I have been taught to regard myself as the fool of the family, a professional ne’er-do-well.” From 1910 to 1959 he held between 60 and 85 different jobs: in the engineering shops of 30 motor car companies including Rolls-Royce and Ford, as a nurse to a wealthy invalid, as a Post Office Savings Bank clerk, a pavement artist, a carnival sideshow assistant, an English tutor in Paris…

He loved puzzles and wordplay, especially palindromes. He is best known for creating “A man, a plan, a canal – Panama.” There is an 8-page biography of him here, including 100 palindromes. Leigh Mercer died in 1977.
