Overview * Combines an in-depth overview of the theory with problems presented at several Mathematical Olympiads around the world. Springer Nature Link An Excursion through Elementary Mathematics, Volume I Diophantine equations (including Pell’s equation)

: Limits, derivatives, Riemann's integral, and series of functions. Volume I : Limits

The final volume covers diverse "discrete" topics essential for competitive mathematics.

: Includes classical theorems on congruence, similarity, and the geometry of triangles (e.g., Menelaus and Ceva).
