the first thing we did was added 1,3,5 and 7 together to make 16 then we needed to get to 37, we added the numbers up until we got 37(that was 21) but relised that it was nine numbers we used not ten, so we tried again and our total numbers was 11. finaly we got ten but the number was 38. We looked at our maths chart to help us and found that odd + odd = even so this sum is impossible
