IMO problems do not require advanced mathematical knowledge and instead draw on relatively simple topics such as mechanics, number theory, geometry, and algebra.

“It doesn't require you to really understand like the advanced math.”

“It's basically it's problems about”

“simple knowledge like common mechanics number theory geometry and algebra but then it kind of require you to have very strong problem-solving skills you need to know how to do a contradiction you can know how to create like counter examples you need to do like observation etc and so people treat this as like the one of the”
