Goal: be able to evaluate math competition/textbook/past papers

Edit this issue to research what kinds of mathematical expressions a math student from primary education all the way to tertiary education may encounter, whether in textbooks, past papers or competitions. Proceed to extract examples and make sure we can solve them (albeit with nuances that might not be mentioned at lower education levels, that need to be mentioned specifically). New competitions, textbooks, past papers come out all the time, monitor and track them.

No files, tests, or entry points are named. Start by surveying mathematical expressions from primary through tertiary textbooks, past papers, and competitions, then validate the collected examples with the library. Done means representative cases are tested, unsupported or nuanced cases are explicitly documented, and a way to monitor new sources is defined.
