A seemingly baffling maths problem posted on Facebook by Singaporean television has become an unlikely internet sensation. The puzzle, designed for high-achieving teenagers, asks students to determine the birthday of “Cheryl” based on a series of short statements by “Albert” and “Bernard”. Is it easy to learn how to approach these sorts of problems and should we all be taught this way? Rob Eastaway is director of Maths Inspiration, which puts on public maths lectures, and author of books on maths and everyday life and Laura Clarke is a senior lecturer in education specialising in mathematics at the University of Winchester.
