Hello, for those who are interested I have worked out the correct path (with all the other options) in a flow diagram. Only click on “spoiler” if you have already found the correct path!
Spoiler
The path starts at the top at 1 (first page) and ends via the correct green path at page 42. Between the pages you can see the different options you have (indicated by the arrows). The two red marked pages are dead ends. The other pages are colored gray.
I’ve done my best to make this, but I can’t promise if this is 100% correct. As an example: from page 30, I think you should also be able to go to 31 and 38 (instead of the question mark in the book) because these numbers satisfy the sum written out where the result is always 3.
