Lange dachte ich, die erste Ziffer der Summe müsste die gerade Ziffer sein... aber es kann halt auch die ungerade sein... :grins:

I received some comments to this puzzle stating it needs heavy T&E to be solved. I tend to avoid T&E in all my puzzles, so also this one is solvable without heavy T&E, although one educated guess is necessary to proceed. I solved the puzzle myself this morning, and have to admit the guessing step is earlier in the process than I had in mind, but still...
Don't give up! If you solved it, you can read how the first 1/3 of the puzzle can be solved by pure logic, and that should be already interesting for learning purposes.
