A SE­RIES OF MATHS-BASED PUZ­ZLES BY DAVID WELLS Ver­bal Arith­metic This type of puzzle was pi­o­neered by Henry Du­deney, one of the great “prob­lemists” of the late 19th cen­tury and the early decades of the 20th. Du­deney was born in the vil­lage of May­field in East Sus­sex in 1857. His pa­ter­nal grand­fa­ther was a self-taught math­e­ma­ti­cian and as­tronomer who started as a shep­herd and raised him­self to the po­si­tion of school­mas­ter in Lewes. Du­deney’s fa­ther was also a school­mas­ter, but Du­deney him­self did not go to col­lege and in fact was a self-taught math­e­ma­ti­cian. In his early puzzle-set­ting ca­reer, Du­deney col­lab­o­rated with the Amer­i­can Sam Loyd, who com­posed last Sun­day’s puzzle about Casey’s Cow. Here’s an ex­am­ple of Ver­bal Arith­metic cre­ated by Du­deney, pub­lished in The Strand Mag­a­zine in 1924:
