Math Competition Strategies
Techniques for olympiad problems.
Key idea
Techniques for olympiad problems.
In depth
Common techniques: look for invariants, symmetry, pigeonhole, induction, clever substitutions, extremal principles, working backwards, and trying small cases. Manage time and check answers by independent methods.
Worked example
To find the number of ways with a constraint, count the complement instead.
Real-world uses
- Preparing for olympiads and maths challenges through structured problem-solving methods
Common mistake
Spending too long on one problem without moving on and returning later.
How to learn this
- Read the key idea and say it in your own words.
- Work through the worked example, then try a similar problem.
- Use the interactive lesson’s visual and mini-quiz to check the pattern.
