The 64th International Mathematical Olympiad (IMO) 2023 was held in Chiba, Japan, from July 2 to July 13, 2023. This prestigious competition brought together top high school mathematicians from around the world.
IMO 2023 Overview
- Host Country: Japan (Chiba)
- Dates: July 2–13, 2023
- Participants: 618 students from 112 countries
- Format: Two-day exam with six problems (each day: 3 problems in 4.5 hours)
- Scoring: Each problem is worth 7 points, leading to a total of 42 points.
Question Pattern & Topics
IMO problems are designed to test deep mathematical insight and problem-solving skills. The questions are divided into six broad areas:
1. Algebra
- Functional equations
- Polynomials
- Inequalities (AM-GM, Cauchy-Schwarz, etc.)
- Sequences and series
2. Combinatorics
- Counting principles
- Graph theory
- Pigeonhole principle
- Recursion and induction
3. Geometry
- Euclidean geometry (circles, triangles, quadrilaterals)
- Transformations (inversion, homothety, etc.)
- Coordinate geometry
4. Number Theory
- Prime numbers and divisibility
- Modular arithmetic
- Diophantine equations
- Congruences
Example Problem from IMO 2023
One of the IMO 2023 problems was:
Problem 1 (Algebra - Functional Equations)
Find all functions such that for all real numbers ,
(Solution requires deep understanding of functional equations and algebraic manipulation.)
