I wrote a list of consecutive numbers 0-9, remembering 3 was not to be used (already used in the algorithm).
I then worked on the top 4 digits using the clues given. I chose 4,5,6 and 9. 4 +5=9 so 9 was placed as the 3rd digit. From there I made a list of the numbers in different positions until it worked out. Once the 4 digits were in the correct places the rest of the clues matched my answer.
5694x3=17082 was my answer.
