Shannon, Ellie, Stephen, Tom and Zachary all at Trinity Middle School, Newport, Isle of Wight found solutions to "Reach 100". Shannon and Ellie realised that the numbers 12, 14, 27 and 47 total 100. Tom and Stephen each suggested a different way the digits could be arranged in the grid:
1 2
4 7
1 4
2 7
Zachary spotted both these - very well done - and also sent this solution:
2 3
1 8
Kirsty, from St Aldhelms School in Poole, went one stage further. She rearranged these digits to make the final solution:
2 1
3 8
