IMO problems draw on basic mechanics, number theory, geometry, and algebra, while requiring strong problem-solving skills, including proof by contradiction, constructing counterexamples, and making observations.

“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”
