For all those that still can't solve it, this answer pretty much sums it up:
1. Write out the digits 0-9 on a bit of paper. Then take your first hint - for example 3=7.
2. On the row below, write "7" below the "3". Then continue the digits in order on the second row - wrap around when you get to the end, like this:
You don't have to write it on paper, the other circle with numbers there can serve the same purpose :)
You don't need the spreadsheet, you don't need paper, you don't need to calculate anything. Just use the circles. (of course, you can also brute force it if you haven't revealed all the clues - there's a few posts above that tell you how). If you have the clues, align the circles for each clue separately and then read the numbers that are given by your flower packs. If it doesn't work try the second clue, and the third.
For example, if your first clue says 5=7 then spin the large circle so that the number "5" on the small one (immovable) aligns with number "7" on the big one. Now, without moving the circles check the numbers. If, let's say your flower packs are 4,6,7 (from top to bottom, reading clockwise) then see which number on the big circle is aligned with 4, then with 6 and finally with 7 on the small one (you should get 6, 8, 9 in this example). Now move the big circle so that 6 is aligned with the arrow, click on the big red blob, move the circle again to align the arrow with 8, click the red thing and finally align the arrow with 9 and click again. If it doesn't work, repeat for the next clue.
