Algebra
Olympiad algebra lives at the intersection of inequalities, identities and structure. Teachers study how estimates, rewrites, and purposeful substitutions reveal the structure of a problem. Symmetric polynomials, factorisations, and functional equations provide the working language.
- Classical inequalities, arithmetic and geometric mean, Cauchy Schwarz, rearrangement, and power mean
- Symmetric and homogeneous polynomials, Newton's identities
- Functional equations and the discipline of substitution
- Polynomial roots, Vieta's relations and Lagrange interpolation
- Algebraic structure in number theoretic problems
