We worked out the answers by using a system every time we tried a new way of finding a new way of finding a combination we changed carriage one by moving it to one number after finding all the combinations for each carriage one being the numbers 1-5 we started changing carriage two in the same way after finding all ways using 2 carriages we added a carriage and went through the same process.
