Mathematics

Worked solutions to several mathematical problem collections. Each collection has its own index with the full list of problems.

The International Mathematical Olympiad sets the hardest problems given to high-school students anywhere, six a year since 1959. Around the contest sit its two feeder collections: the IMO Shortlist, the pool from which each year's jury picks the final six, and the IMO Longlist, the wider set of problems that participating countries propose before shortlisting.

The Art of Computer Programming collects solutions to the exercises in Donald Knuth's volumes, ranging from short warm-ups to research-grade questions.

Kvant draws on the long-running Russian magazine of mathematics and physics for school students, with each problem translated and solved.
