I made quite a few contest-style math problems across highschool and undergraduate levels. Feel free to give them a shot! The problems get progressively more difficult
Rough difficulty chart... Please note that "Easy" means easy relative to the rest of these problems, not easy in general Highschool section Easy: P1 (number theory) P2 (geometry) P3 (functional equations) P4 (polynomials) P5 (combinatorics) Medium: P6 (combinatorics) P7 (number theory) P8 (combinatorics) P9 (algebraic inequality) P10 (geometry) Difficult: P11 (algebraic inequality) P12 (number theory) P13 (combinatorics) P14 (functional equations) P15 (geometry) Undergraduate section Easy: P1 (functional equations) P2 (abstract algebra) P3 (number theory) P4 (linear algebra) P5 (multivariable analysis) (first solve by: @1170008152) Medium: P6 (linear algebra) P7 (analysis) P8 (analysis) P9 (linear algebra) P10 (polynomials) P11 (functional equations) Difficult: P12 (real analysis) P13 (number theory)
