Mathematische Schülerbücherei some questions

[pier4r]

Thanks for the pointers!

I got one that is "gut gedacht ist halb gelöst" (think well is half of the problem ???) from a book box with a label "zu verschenken". The quality didn't seem so bad (maybe the book was always closed though).

For project euler, I know that too yes, although it goes in the direction of the international math olympiad (at least from a certain problem on).


About the book from 2001. https://www.amazon.de/-/en/Pavel-S-Alexa...3817116586 122 € wow. I was thinking they were "cheap" as people see them as old. (ah found the same book for 8 € )

I was thinking like this: https://www.amazon.de/-/en/Reinhard-Krieg/dp/B002OS2LIU (2 € , nr 86 of the series)
