The SUMS Puzzle Hunt is being held this week, beginning at noon today (Monday). This online event is designed to encourage thinking mathematically in ostensibly non-mathematical contexts. It also serves to advertise the School of Maths and Stats to an international audience, targeting final-year school and university students.
