Picking the winners
We received 76 entries, 63 of which were correct.
So without further ado, the winner of the Chalkdust Issue 06 crossnumber competition is Jessica Rose Marsh, who wins a £100 goody bag from Maths Gear. The runners-up, and winners of Chalkdust T-shirts, are Patrick Newberry, Amy Rogers and Rata Ingram.
Thank you to everyone who entered the crossnumber competition! The competition will return in Issue 07 of Chalkdust, released in March…
