These questions tend to be a bit long (and maybe tedious, depending on how much you love maths). They may not be the most exciting, but they do test accuracy, so if you just need to practise, these are the ones for you.
Not tough, but how efficiently can you solve them? Useful for training your mathematical speedrunning.
These questions often require noticing a particular trick, or may be significantly easier if you do spot it. These are really good for building up your intuition and training for diverse problems.
Questions that look horrific. There’s a good chance you’ll look at it and think “what is this.” or “hell nah I’m not doing that”.

If you’re looking to impress others who aren’t as far down the wormhole as you, these are pretty wow-inducing.
These questions give you a right fright at first glance, but aren’t actually that difficult. Like HORROR, but less horrible. Probably.
Looks like that, eh? Heads up: it isn’t. Laced with ditches for you to step into if you’re not careful. Fun for sharing with others.
Beware the S-I+G-N error(s)!
Warning: features exceptionally juicy maths that may be conducive to questionable noises. Reader discretion is advised.
Sometimes, maths is just so fun.
These ones are exceptionally tough with a potentially really non-obvious solution, especially if you haven’t seen this style of question before.
May require advanced knowledge.
Heh, get played. Questions that pull a fast one on you.
Left as an exercise to the reader.
I mean, π\pi just shows up everywhere, y’know?
Why would you do this to me...
