Hi everyone. Apologies for the delay in producing the June problems and also in responding to those of you who have sent in solutions to the May problems. I’ve had a few unexpected events chew up rather large blocks of my time. However, here at least are the June problems, and the April solutions for you.
From this month forward, the monthly problems will be a selection of problems used in previous sets of “September problems”. This month, it’s four of the easiest problems from 2006.
