Nichts besseres zu bloggen?

Dann gib damit an, alle Fragen richtig— weise auf ein Quiz hin, z.B. das (zum Jahr der Mathematik passende) „Große Rechen-Rätsel“ von Spiegel Online (Artikel dazu) mit 15 Fragen – drei zu vervollständigende Zahlenreihen, ansonsten kleine Rechenaufgaben.

Also viel Spaß – und nicht schwindeln (was bei SpOn-Quizzes leider viel zu einfach ist…)! :mrgreen:

All inputs are optional. The e-mail address won't be published nor shared.

  • Moderation: Comments from first-time commentators must be approved manually before they appear.
  • Behave yourself! No insults, no illegal content, etc.! Should go without saying, don't you agree...?
  • Website: I don't mind blogs with ads, but purely commercial links are not welcome and will be deleted. Just like pure spam comments.
  • E-mail notification on new comments: You will have to activate this function once with a link in an automatically sent confirmation mail. These notifications can be disabled again with the link in every mail, of course.
  • Twitter: If you got a Twitter account, you can enter your Twitter name (with or without the @, doesn't matter) which will then be displayed next to any comment (including old ones) that contain the same e-mail address. (Which also means that you must fill in that e-mail field.)
